    Cell plate assembly for a solid state compressor, solid state compressor, and method of operating a solid state compressor The present invention relates to a cell plate assembly for adjoining an anode side of a membrane-electrode assembly of a solid state compressor.
    The invention further relates to a first cell plate and a second cell plate for use in a cell plate assembly according to the invention.
    The invention also relates to a solid state compressor for electrochemically compressing a fluid, comprising a cell plate assembly according to the invention.
    Finally, the invention relates to a method for operating such a solid state compressor.
    While conventional mechanical compressors use mechanical means such as pistons or rotors for compressing a fluid, solid state compressors rely on the electrochemical transport of said fluid through a membrane using an ion transport mechanism.
    In order to compress the working fluid electrochemically, a solid state compressor generally comprises a compression cell composed of one or more stacked membrane-electrode assemblies (also called MEA, in English “membrane electrode assembly”). The MEA's electrodes are connected to a power supply to maintain an electrical potential difference between the electrodes.
    This potential difference is necessary to electrochemically displace the ionized working fluid through the proton exchange membrane (commonly called PEM, in English “proton exchange membrane”) against the pressure gradient which exists across the membrane.
    The direction of the electric current thus determines the direction of ion transport, in which the low pressure working fluid is ionized at the positively charged anode and is recombined with the separated electrons on the high pressure cathode side of the MEA.
    Solid state compressors have a number of significant advantages over mechanical compressors.
    This is because solid state compressors have no moving parts and are generally compact in design.
    In addition, solid state compressors make it possible to compress fluids at very high pressures, up to 1000 bars and more, with operating efficiencies greater than those of mechanical compressors. Another advantage of electrochemical compression is that it makes it possible to purify the working fluid, since the membrane only allows the ionized working fluid to be transported. A commonly known solid state compressor is the electrochemical hydrogen compressor in which hydrogen is fed to the membrane-electrode assembly and oxidized to protons and electrons. The protons are then driven through the membrane and the electrons are transferred by an external circuit, after which the protons and electrons are reduced to molecular hydrogen. In this process, hydrogen moves against a pressure gradient from an area of low pressure to an area of high pressure, resulting in an increase in pressure across the membrane. The compression of other working fluids, such as water or ammonia, is however also possible.
    For the supply of working fluid to the low pressure (anode) side of the membrane-electrode assembly, the working fluid is typically transported through a number of channels which extend parallel to the membrane-electrode assembly. These channels can be arranged in a bypass flow configuration in which the channels are connected on one side to a supply line for the supply of working fluid to the multiple channels and, connected on an opposite side to the multiple channels. a pipe or discharge line for discharging a fraction of the working fluid which is not transported through the membrane. A possible disadvantage of this flow configuration is that a recirculation process may be necessary to recycle excess working fluid collected by the drain.
    Alternatively, the channels can be arranged in a dead end configuration in which the channels are connected on one side to the supply line, but in which the opposite side of said channels is designed as a dead end. bag. This flow field design forces the working fluid to pass through the diaphragm only instead of allowing a fraction of the working fluid to bypass the diaphragm. An advantage of this channel configuration is that the need for a recirculation process as mentioned above is avoided. However, this channel configuration has its own drawback due to the fact that the proton exchange membrane has a purifying function, allowing transport only of the ionized working fluid.
    No working fluid feed stream will be completely pure. Impurities (such as nitrogen and liquid water) present in the working fluid will accumulate near the closed or dead ends of the channels because the impurities cannot move through the membrane. The accumulated impurities will therefore at least partially block the net flow of working fluid in the direction of the dead end ends, thereby reducing the mass transport of the working fluid through the membrane. This suboptimal mass transport of working fluid directly affects the efficiency and productivity of the solid state compressor.
    An object of the invention is therefore to improve the supply of working fluid to the low pressure side (anode) of the membrane-electrode assembly, or at least to provide an alternative to the solutions mentioned above.
    The invention thus provides a cell plate assembly for adjoining an anode side of a membrane-electrode assembly of a solid state compressor, comprising: a first cell plate having a first channel structure incorporated therein. therein comprising multiple channels extending over at least a portion of the cell plate and extending parallel to a first surface of the cell plate, and a second cell plate including a first surface interfacing with the first surface of the first cell plate and having a second channel structure incorporated therein comprising multiple channels extending over at least a portion of the cell plate and extending parallel to the first surface of the cell plate, wherein the channels of the respective channel structures are interconnected at the interfacing surfaces of the first and second cell plates and wherein the second cell plate cell comprises a number of passages connecting the second channel structure incorporated therein to a second surface of the second cell plate opposite the first surface of the second cell plate, wherein the channels incorporated in the second cell plate form an angle with the channels incorporated in the first cell plate.
    A channel according to the invention is to be understood as a recess of a depth less than a thickness of a first cell plate from a first surface.
    In other words, the device according to the present invention therefore comprises a first cell plate, having a length and a depth, comprising a first channel structure incorporated therein, comprising multiple channels extending over at least one. part of the cell plate, at least with a length greater than half the length of the first cell plate and extending parallel to a first surface of the cell plate, with the multiple channels recessed with a depth less than the depth of the first cell plate from a first surface, and extending parallel to the first surface of the cell plate, and also includes a second cell plate, having a length and a depth, including a first interfacing surface with the first surface of the first cell plate and having a second channel structure incorporated therein comprising multiple recessed channels with c a depth which is less than the depth of the second cell plate, and thereby forming a partially recessed channel through the plate from the first surface of the cell plate, extending over at least part of the plate of the cell plate and extending parallel to the first surface of the cell plate along the interfacing surfaces.
    This configuration optimizes the distribution of the working fluid, so that the working fluid is optimally distributed before passing through the number of passages to the second surface of the second cell plate.
    The channels are preferably longer than half the length of the first cell plate.
    At the heart of a solid state compressor is a membrane-electrode assembly, comprising a proton exchange membrane sandwiched between two electrodes which respectively form the anode and the cathode.
    The cell plate assembly mentioned above is positioned on the anode side, which constitutes the low pressure side of the membrane-electrode assembly. The cell plate assembly functions as a flow field plate assembly by means of which low pressure working fluid, through the channels of the channel structures of the first and second cell plates, is supplied to said side. anode. The second surface of the second cell plate of the cell plate assembly thus faces the membrane-electrode assembly and, in one possible configuration, is in direct contact with said membrane-electrode assembly.
    The working fluid first passes through the multiple channels of the channel structure of the first cell plate. These channels are typically parallel to each other so that the individual channels do not cross. Since the channels extend over at least a portion of the cell plate parallel to the first surface of the cell plate, which first surface extends parallel to the surface of the membrane, working fluid is transported through said channels. channels in one direction along the membrane surface. The second cell plate interfaces with (contacts) the first surface of the first cell plate with a first surface thereof. The channel structures of the first and second cell plates are interconnected at this interface surface, allowing working fluid to flow through the channels of the second channel structure of the cell plate. Since the channels of the latter channel structure also extend over at least a part of the cell plate parallel to the first surface of the cell plate, which first surface also extends parallel to the membrane surface, the working fluid is transported through said channels in a direction along the surface of the membrane. The multiple channels of the channel structure of the second cell plate also typically extend parallel to each other so that the individual channels do not intersect. Since the channels incorporated in the second cell plate form an angle with the channels incorporated in the first cell plate, the direction of flow of the working fluid will be different between said channels.
    The inclusion of an angle should be understood as any angle other than 0 degrees,
    causing the channels of the channel structures of the first and second cell plate to cross. At the crossing points, the channels of the second cell plate are connected to the channels of the first cell plate, thereby interconnecting the different parallel channels in the channel structure of the first cell plate. I! As a result, the working fluid in the separate channels of the first cell plate is laterally redistributed through the channels in the second cell plate, increasing the uniformity of mass transport on the membrane surface. Further, with the redistribution of the working fluid, the impurities present in the working fluid are also distributed more evenly over the channels of the second cell plate. The accumulation of impurities will therefore affect to a lesser extent the distribution of the working fluid on the surface of the membrane. As the accumulation of impurities has a less impact on the distribution of the working fluid on the membrane surface and therefore on the performance of the compressor, cleaning of the channel structures can be carried out at extended intervals. The cleaning of the channel structures is carried out by purging, which involves letting the working fluid flow through the channels in the opposite direction. This can be achieved by reversing the direction of the electric current, changing the polarity of the electrodes and thereby reversing the electrochemical transport of the working fluid through the membrane. By interconnecting the individual channels of the first channel structure of the cell plate through the channels of the second channel structure of the cell plate, the purge efficiency is improved. This is because the interconnections eliminate dead ends or dead ends in the channels of the interconnected channel structure which would otherwise trap impurities present in the working fluid. Thanks to the absence of a dead end, the return of the working fluid and the impurities it contains can now flow in only one direction, allowing the channels to be cleared.
    | It is possible that the channels of the second channel structure are substantially perpendicular to the channels of the first channel structure, which means that the channels of the second channel structure and the channels of the first channel structure form an angle of approximately 90 degrees. By allowing the channels of the first and second channel structures of the cell plate to intersect at angles of approximately 90 degrees, an even more uniform lateral redistribution of the working fluid over the channels of the second channel structure of the cell plate is achieved. plate.
    In addition, the perpendicular arrangement of the channels creates as little overlap as possible between the channels, which in turn will lead to a more solid construction, better able to cope with the very large pressure differences that exist between the interior and the interior. outside the canals.
    Indeed, the pressures to which the cell plates are subjected are generally equal to or greater than the pressures of the pressurized working fluid on the cathode side of the membrane-electrode assembly, while the pressures inside the channels of the assembly. of cell plate are equal to those of the low pressure working fluid.
    In a preferred embodiment of the cell plate assembly according to the invention, the channels of the first channel structure have a diameter greater than that of the channels of the second channel structure.
    The coarser channels of the first channel structure are preferred from the point of view of mass transport because the larger diameter of these channels allows in particular a greater flow of working fluid and minimizes the clogging of the channels due to the accumulation of water. 'impurities.
    The finer structure of the channels of the second cell plate, on the other hand, allows a more even distribution of the working fluid over the surface of the second cell plate while maintaining a load capacity necessary to cope with the pressure differences.
    The spacing between consecutive channels of the second channel structure is generally chosen to be smaller than the spacing between consecutive channels of the first channel structure.
    The channels of the channel structure of the second cell plate have holes along their length on one side of the channels facing the second surface of the second cell plate, thereby creating the passages connecting the channels to the second surface of the cell. second cell plate.
    Even distribution and low spacing between these holes will improve the distribution of the working fluid on the anode side of the membrane surface.
    Therefore, the spacing between the holes of two adjacent channels is preferably kept as small as possible, which is achieved by a small spacing between the adjacent channels of the second cell plate.
    This reduced spacing, however, is only possible if the diameter of these second cell plate channels is kept smaller than that of the more spaced but larger diameter first cell plate channels in order to avoid compromising the integrity of the cell. cell plate due to excess open spacing.
    As mentioned earlier, the channels of the second channel structure of the second cell plate are provided with small holes along their length to allow the working fluid to diffuse to the second surface of the second cell plate. If these holes are small enough, generally on the order of 100 microns or less, the second cell plate is capable of directly supporting the membrane-electrode assembly. Since the pressure differences between the low pressure working fluid and the compressed working fluid are generally very large, an equally large pressure difference exists on the different sides of the membrane-electrode assembly. The membrane, which generally consists of a thin layer of polymer, must therefore be sufficiently supported. If the holes in the channels of the second cell plate are too large, the membrane will be pushed through these holes under the influence of the large pressure difference, which may lead to rupture of the membrane.
    The first cell plate channel structure is generally connected to a supply line or line for supplying a working fluid through the channels of said channel structure. This feed line can be connected to the individual channels of the channel structure via one or more subdivisions of said feed line. Typically, the supply line has a larger diameter than the channels of the first channel structure of the cell plate to have sufficient capacity to supply the working fluid to each of said first channels of the cell plate.
    As another means of increasing the power supply capacity, the first cell plate channel structure can be connected to at least two separate power lines, each connecting to different, and preferably opposite, ends of the structure. channel. Another advantage of feeding the first cell plate channel structure to its multiple ends is that a better distribution of the mass transport of the working fluid over the channels of the channel structure can be achieved.
    In one possible embodiment of the cell plate assembly, the first plate channel structure comprises two separate channel systems, each connected to a different row of separate feed lines, in which the channels of the cell plate systems. separate canal are dead-end.
    In this dead-end configuration of the channel system, the working fluid in the channels of the first cell plate will flow in a single direction from the single supply line to the channels of the second channel structure. cell plate, which benefits the flow rate of the working fluid.
    By using multiple channel systems, the working fluid supply can be distributed over multiple supply lines, with each channel system remaining connected to a single supply line.
    Since the channel structure of the second cell plate does not redistribute the impurities present in the working fluid, said impurities accumulate at least partially near the dead-end ends of the channels to the point that the The rate of diffusion of impurities towards the feed line at least partially opposes the flow of the working fluid towards the dead end ends.
    This results in a decrease in the concentration of the working fluid along the length of the channels towards the ends.
    In order to redistribute the problem of impurity build-up, the channels of the separate channel systems can contain each other, thus forming an interdigitated channel structure in which the channels that follow each other are part of different channel systems. .
    Thanks to this interdigitated cul-de-sac configuration of the channel systems, a more uniform distribution of the working fluid on the membrane can thus be obtained despite the presence of accumulated impurities.
    Alternatively, the channel structure may comprise a single, continuous channel system, the channels of which are connected at opposite ends to separate feed lines.
    This channel configuration does not include dead ends.
    sac inherent in the cul-de-sac configurations described above, so that impurities do not accumulate locally within the first channels of the cell plate.
    Impurities will therefore not affect the distribution of the working fluid over the membrane to the same extent as it would with any of the dead end configurations described above.
    It is also possible for one of the feed lines to function as a discharge line so that the channels are effectively arranged in a bypass flow pattern.
    The channel structures of the first and second cell plates may be formed by elongated recesses provided in the first surfaces of the first and second cell plates.
    These elongated recesses are easily formed in the cell plates, for example by a milling process, without compromising the inherent strength and load carrying capacities of the cell plate material.
    By placing the recessed portion of the respective first surfaces of the first and second cell plates directly on top of each other, closed channels are formed which contact each other at the points where the recesses in the respective cell plates are formed. cross.
    The invention also relates to a first cell plate for use in a cell plate assembly according to the invention.
    The invention also relates to a second cell plate for use in a cell plate assembly according to the invention.
    The advantages of using such a first cell plate and such a second cell plate adjoining an anode side of the membrane-electrode assembly of a compressor
    - Solid state, as well as the possible characteristics of these cell plates are already discussed above in relation to the cell plate assembly.
    The invention further relates to a solid state compressor for electrochemically compressing a fluid, comprising a membrane-electrode assembly contained between a cell plate assembly according to the invention and a fluid collection plate, wherein an anode side of the The membrane-electrode assembly faces the second surface of the second cell plate of the cell plate assembly, and a cathode side of the membrane-electrode assembly faces the fluid collection plate.
    The fluid collection plate thus functions to collect and transport the compressed fluid away from the compressor cell.
    The solid state compressor can be oriented such that the anode side constitutes the lower side of the membrane-electrode assembly, so that the cell plate assembly is also positioned on the lower side of the membrane-electrode assembly. electrodes.
    However, it is also possible that the solid state compressor is oriented such that the anode side constitutes the upper side of the membrane-electrode assembly. The solid state compressor can be an electrochemical hydrogen compressor, but it can also be configured to compress other working fluids such as water or ammonia. The principle of operation of these solid state compressors is the same, i.e. they compress the working fluid by letting it pass through a membrane-electrode assembly. Finally, the invention relates to a method for operating a solid state compressor according to the invention, comprising the steps: A) supplying a fluid via a supply line to the channels of a first structure of cell plate channel, B) passing fluid from the channels of a first cell plate channel structure to the channels of a second cell plate channel structure, C) distributing fluid from the channels d 'a second cell plate channel structure through passages on an anode side of a membrane-electrode assembly, D) ionizing the fluid on the anode side of the membrane-electrode assembly, E) passing the fluid ionized through a proton exchange membrane of the membrane-electrode assembly, which compresses the fluid, and E) collecting the compressed fluid from a cathode side of the membrane-electrode assembly. The advantages of this method for the operation of a solid state compressor and for the supply of working fluid to the anode side of the membrane-electrode assembly in particular are already explained in detail with regard to the various embodiments. possible of the cell plate assembly according to the invention.
    The method may include the subsequent step of purging, in which steps A-F are performed in reverse order, thereby removing impurities from the channel structures on the anode side of the membrane-electrode assembly. As already mentioned in the discussion of the various embodiments of the cell plate assembly, the interconnection of the individual channels of the first cell plate channel structure by means of the channels of the second channel structure cell plate improves purge efficiency. This is because the interconnections make it possible to effectively eliminate any dead ends or dead ends in the channels of the interconnected channel structure which would otherwise trap the impurities present in the working fluid. Due to the absence of dead ends, the return of the working fluid which is accomplished by the purge can flow in only one direction to the inlet supply (which, during the purge, acts as a discharge), thus carrying with it all the impurities accumulated in the channels on the anode side of the membrane-electrode assembly.
    In order to further explain the invention, embodiments given by way of non-limiting examples are described with reference to the figures, among which: Figure 1 shows a perspective view on the first surface of a first cell plate of a cell plate assembly according to the invention, Figure 2 shows a perspective view on the first surface of a second cell plate of a cell plate assembly according to the invention, Figure 3 shows a cross section of a cell plate assembly according to the invention perpendicular to the first and second cell plate surfaces, and Figures 4a-4c show schematic representations of different possible configurations of channel structure as provided in the cell plates of a cell plate assembly according to the invention.
    The figures show specific exemplary embodiments of the invention and should not be construed as limiting the invention in any way or form. Throughout the description and figures, corresponding reference numerals are used for corresponding elements.
    A solid state compressor according to the invention comprises a membrane-electrode assembly enclosed or contained between a cell plate assembly according to the invention and a fluid collection plate to form a compressor cell. The cell plate assembly includes a first cell plate and a second cell plate, wherein the second cell plate adjoins the anode side of the membrane-electrode assembly. The compressor cell is delimited by two current collector plates which form an interface between the first cell plate and the fluid collector plate respectively. The current collector plates serve as a passage for the electrical connection of the electrodes to a power supply. The compressor cell is attached on opposite sides between an enclosure that maintains pressure on the cell stack.
    The enclosure comprises two flanges which are joined together near their peripheral edges by a set of bolted joints formed by bolts and nuts.
    Figure 1 shows a perspective view of the first surface 21 of a first cell plate 20 of a cell plate assembly according to the invention.
    The first cell plate 20 is provided with multiple protrusions 22 each provided with recesses 23 which can wrap around frame parts of the compressor housing, thereby maintaining the first cell plate 20 at a fixed location bounded by the second plate. cell (see figure 3) and other parts of the compressor cell.
    The first cell plate 20 is further provided with outlets 24 for the working fluid supply lines.
    The outputs 24 are each connected to a number of channels 25 which serve as subdivisions of the power line.
    These subdivisions 25 transform into multiple parallel channels 26 which together form the channel structure 27 of the first cell plate 20. Each of the channels 26 is thus formed by elongated recesses provided in the first surface 21 of the first cell plate. 20. In the illustrated configuration, the channel structure 27 comprises two separate and interdigitated channel systems 28, 29, each connected to a different outlet of the working fluid supply line 24. Other configurations of the working fluid structure. channel are however also possible, as shown in more detail in Figures 5a-c.
    Figure 2 shows a perspective view of the first surface 31 of a second cell plate 30 of a cell plate assembly according to the invention.
    Like the first cell plate 20, the second cell plate 30 is provided with multiple protrusions 32 with recesses 33 which can wrap around frame portions of the compressor housing.
    The second cell plate 30 is further provided with holes 34 for the passage of the supply lines.
    The second cell plate 30 also includes multiple parallel channels 35 which together form the channel structure 36 of the second cell plate 30. Each of the channels 35 is thus formed by elongated recesses provided in the first surface 31 of the cell. second cell plate 30. The mutual distance between successive channels 35 of the second cell plate channel structure 36 is smaller than the mutual distance between successive channels 26 of the first cell plate channel structure 27. Further, the number of channels 35 in the second cell plate channel structure 36 exceeds the number of channels 26 in the first cell plate channel structure 27.
    Figure 3 shows a cross section of a cell plate assembly 40 according to the invention perpendicular to the first and second cell plate surfaces. The cell plate assembly 40 includes a second cell plate 41 and a first cell plate 42, wherein each of the cell plates 41, 42 is provided with its own channel structure 43, 44. The channels 45 of the second cell plate channel structure (second cell plate channel structure) 43 extend perpendicular to the channels 46 of the first cell plate channel structure (first cell plate channel structure) 44. The channels 45,46 of the two channel structures 43,44 thus extend in the plane of their respective cell plates 41,42. The channels 45,46 of the two channel structures 43,44 are interconnected at their points of intersection 47 to create a continuous flow path for the working fluid to be supplied to the membrane-electrode assembly. The second cell plate 41 further includes a number of passages 48 connecting the channel structure 43 to the second surface 49 of the second cell plate 41, which adjoins the membrane. A fluid collector plate 50 positioned on the cathode side of a neighboring membrane-electrode assembly is also shown. Fluid collector plate 50 is provided with holes 51 for transporting compressed working fluid away from the compressor cell.
    Figures 4a-4c show schematic representations of different possible configurations of channel structure as provided in the cell plates of a cell plate assembly according to the invention. Figure 4a shows, as for the cell plate shown in Figure 2, a channel structure 60 of the first cell plate comprising two channel systems 61, 62 containing / nested in one another, thus forming an interdigitated channel structure 60 in which successive channels 63 are part of different channel systems 61, 62 which are connected to separate fluid supplies 64. Each of the channels 63 is here dead-end. However, since the channels 65 of the second cell plate channel structure 66 interconnect the separate channels 63 of the first cell plate channel structure 60 alternately at both ends of the first cell plate channels 63, a semi configuration of bypass is obtained during the purge. Figure 4b shows another configuration with dead end channels 67 of the first cell plate channel structure 68. This time all channels 67 are part of a single channel system connected to a single power supply. fluid 69. However, just as with the configuration shown in Figure 5b, the channels 70 of the second channel structure 71 of the cell plate connect the separate channels 67 of the first channel structure 68 of the cell plate.
    Finally, Figure 4c shows a channel configuration in which the first cell plate channel structure 72 comprises a single, continuous channel system, the channels 73 of which are, at their opposite ends, connected to separate power lines. 74. The first cell plate channel structure 72 thus forms a bypass configuration. Again, the channels 73 of the first cell plate channel structure 72 are interconnected by the channels 75 of the second cell plate channel structure 76.
