    Fuel cell system with ring-shaped reformer
    The present invention relates to a fuel cell system, in particular an SOFC system, comprising a fuel cell stack with an anode section and a cathode section, a reformer for supplying reformed anode gas to the anode section, and an exhaust gas burner for burning anode exhaust gas from the anode section and / or cathode exhaust gas from the cathode section. The invention further relates to a method for operating an SOFC system and a motor vehicle with such an SOFC system.
    AT 513 932 A1 describes a catalyst unit for a high-temperature fuel cell system or an SOFC system with a reformer catalyst of a reformer for processing fuel for a fuel cell and an oxidation catalyst of an exhaust gas burner for exhaust gas aftertreatment of the fuel cell. According to AT 513 932 A1, the oxidation catalytic converter is arranged in a ring around the cylindrical reformer catalytic converter. The gas paths of the oxidation catalyst and the reformer catalyst are separated by a metal tube which receives the reformer catalyst, the metal tube having a sleeve which forms a housing for the reformer catalyst and an inner tube which forms the inner wall of the ring-shaped oxidation catalyst. With such an arrangement, effective heat transfer between the reformer catalyst and the oxidation catalyst or between the reformer and the exhaust gas burner can be realized in a compact manner. For additional heating of the oxidation catalytic converter, a start burner is arranged in the fuel cell system, which can additionally heat or preheat the oxidation catalytic converter, particularly when the fuel cell system is started. It is desirable, particularly for mobile purposes, to keep the number of components and thus the size and weight of a fuel cell system as small as possible.
    WO 2013/187154 A1 discloses a fuel cell module with an exhaust gas burner and a reformer. The reformer has a plurality of reformer lines which run parallel to a longitudinal direction of the exhaust gas burner and at a distance therefrom. The fuel cell module also has an evaporator and a heat 2/26
    PP31438AT
    AVL List GmbH metauscher that are in fluid and / or heat connection with each other via a pipe system. The exhaust gas burner, the reformer, the evaporator and the heat exchanger require a relatively complex pipe system and a correspondingly complicated structure of the fuel cell module.
    The object of the present invention is to at least partially take into account the problems described above. In particular, it is an object of the present invention to provide a fuel cell system, a method for operating the fuel cell system and a motor vehicle with the fuel cell system, in which an effective heat transport between the exhaust gas burner, reformer, heat exchanger and / or evaporator can be implemented in a compact and simple manner, whereby the fuel cell system can be brought up to operating temperature quickly and efficiently, particularly during a starting process.
    The above object is solved by the claims. In particular, the above object is achieved by the fuel cell system according to claim 1, the method according to claim 8 and the motor vehicle according to claim 10. Further advantages of the invention result from the subclaims, the description and the drawings. Features and details that are described in connection with the fuel cell system apply here, of course, also in connection with the method according to the invention, the motor vehicle according to the invention and vice versa, so that with respect to the disclosure of the individual aspects of the invention, reference can always be made to one another.
    According to a first aspect of the present invention, a fuel cell system is provided with a fuel cell stack that has an anode section and a cathode section. The fuel cell system also has a reformer for supplying reformed anode gas to the anode section and an exhaust gas burner for burning anode exhaust gas from the anode section and / or cathode exhaust gas from the cathode section. The reformer is arranged at least in sections in a ring around the exhaust gas burner, wherein
    3/26
    PP31438AT
    AVL List GmbH an inner wall section of the reformer is arranged around the entire circumference or at least substantially completely around an outer wall section of the exhaust gas burner.
    Experiments in the context of the present invention have surprisingly shown that the direct arrangement of the reformer described above around the exhaust gas burner leads to an advantageous heating arrangement in the fuel cell system. In particular for a starting process of the fuel cell system, an effective heat transfer from the exhaust gas burner into the reformer can be realized between the exhaust gas burner and the reformer arranged directly in a ring around it. The reformer preferably adjoins the exhaust gas burner directly, at least in sections, particularly preferably in full. That is, the exhaust burner and the reformer are separated from each other only by a partition portion of the reformer and / or the exhaust burner.
    The exhaust burner is preferably cylindrical. The reformer is preferably designed in the shape of a hollow cylinder and, at least in sections, is arranged in a ring-shaped manner around the exhaust gas burner. That is, the cylindrical exhaust gas burner has an outer circumferential section which is designed corresponding to an inner circumferential section of the hollow cylindrical reformer, this outer circumferential section of the exhaust burner being arranged on the correspondingly configured inner circumferential section of the reformer. This means that not only a compact design of the exhaust burner reformer unit can be achieved. This also enables effective heat transfer between the reformer and the exhaust gas burner. The exhaust gas burner is preferably configured at least in sections in the form of a straight circular cylinder or essentially in the form of a straight circular cylinder. The reformer preferably has a hollow cylinder with a corresponding receiving section for receiving the exhaust gas burner therein. Nevertheless, the reformer and the exhaust gas burner are not limited to the shape of a straight circular cylinder or a corresponding hollow cylinder.
    The fact that the reformer is arranged at least in sections in a ring around the exhaust gas burner means, in particular, that the reformer
    4.26
    PP31438AT
    AVL List GmbH is not arranged around the entire length of the exhaust gas burner and at least in sections in the axial direction of the exhaust gas burner around the entire circumference of the exhaust gas burner.
    The fuel cell system is preferably designed in the form of a SOFC system with a fuel source and an oxygen source. The fuel source is arranged to provide fuel for the anode section. The oxygen source is arranged to provide oxygen to the cathode section.
    The fuel cell stack can have several stacking units. That is, the present invention is not limited to a fuel cell system with a single fuel cell stack. Rather, the fuel cell system can have a plurality of fuel cell stacks.
    The exhaust gas burner can have heat-conducting elements on an outer peripheral surface of the exhaust gas burner, which protrude from the outer peripheral surface of the exhaust gas burner in a protruding manner into the reformer or into a fluid guide section of the reformer. As a result, heat transport between the reformer and the exhaust gas burner can be improved. The heat-conducting elements can be designed in the form of fins and / or ribs. The heat transfer between the reformer and the exhaust gas burner can be improved in a simple and inexpensive manner by means of ribs and / or fins on the outer peripheral surface of the exhaust gas burner. As an alternative or in addition to the ribs and / or the fins, a helical rib can be arranged on the exhaust gas burner, which surrounds the exhaust gas burner on the outer circumferential surface of the outgoing burner in the axial direction of the exhaust gas burner. As a result, the path that the anode gas travels on the hot exhaust gas burner can be lengthened and an appropriately effective heat transfer between the exhaust gas burner and the reformer can be realized.
    According to a development of the present invention, it is possible for a fuel cell system to have an evaporator for evaporating anode gas downstream of the exhaust gas burner and upstream of the reformer, and a heat exchanger to be arranged downstream of the evaporator, the heat 5/26
    PP31438AT
    AVL List GmbH metauscher, for heating the reformer or anode gas in the reformer, on the reformer or in the vicinity of the reformer. The evaporator is preferably arranged directly behind or after the exhaust gas burner. By arranging the evaporator directly downstream of the exhaust gas burner, the anode gas which flows over the evaporator in the direction of the reformer can be effectively heated or overheated. Because the exhaust gas from the exhaust gas burner is directed via the evaporator to the heat exchanger, which is arranged on the reformer, the anode gas can also be heated or overheated by the exhaust gas from the exhaust gas burner before the exhaust gas is conducted into the surroundings of the fuel cell system becomes. For heating the anode gas by the exhaust gas of the exhaust gas burner, a first fluid line section of the evaporator, through which the exhaust gas flows from the exhaust gas burner, is in thermal communication with a second fluid line section of the evaporator, through which the anode gas flows.
    Anode gas is to be understood in particular as a liquid or gaseous hydrocarbon which is fed to the reformer from a fuel source via the evaporator in order to be conveyed further to the anode section by the reformer.
    The fuel can e.g. B. hydrogen, ethanol, methane, or diesel. In addition, exhaust gas in the context of the present disclosure is understood to mean anode and / or cathode exhaust gas which is burned in the exhaust gas burner, as a result of which heat is generated which is then available in the evaporator as a heat source. After the evaporator, the exhaust gas is passed through a heat exchanger, which also extracts heat from the (burned) exhaust gas, and released into the environment. After the fuel cell stack, the anode exhaust gas contains unreacted fuel and other constituents which are converted in the exhaust gas burner.
    Furthermore, it is possible that in a fuel cell system according to the present invention, a start burner for heating cathode exhaust gas and / or anode exhaust gas, which flows in the direction of the exhaust gas burner, is arranged upstream of the exhaust gas burner. Using the start burner, the exhaust gas burner or exhaust gas in the exhaust gas burner can be heated particularly quickly during a starting process. The fuel cell system can be started quickly and efficiently. In a fuel cell system according to the invention
    6.26
    PP31438AT
    AVL List GmbH the starting burner can be positioned particularly easily on the cylindrical exhaust burner. It is also conceivable to integrate the start burner in the exhaust burner, which is placed inside the reformer ring.
    Furthermore, it can be advantageous in a fuel cell system according to the invention if the starting burner has a starting burner injector for injecting fuel into the starting burner. This allows a fuel-air mixture in the starting burner to be quickly and easily set to a desired stoichiometric mixing ratio. In this way, a first, for example sub-stoichiometric, mixing ratio can be set during a starting process of the fuel cell system and then a second, for example stoichiometric or super-stoichiometric, mixing ratio can be set in a simple and rapid manner. With the help of the start burner injector, a quick and efficient starting process of the fuel cell system can be promoted in a simple manner. In the present case, fuel is preferably to be understood as a fluid containing hydrogen or hydrocarbons.
    Furthermore, it is possible that in a fuel cell system according to the present invention, the exhaust gas burner for the combustion of the anode exhaust gas and / or the cathode exhaust gas has an exhaust gas burner catalytic converter, in particular a cylindrical oxidation catalytic converter. Using the exhaust gas burner catalytic converter, the exhaust gas burner can basically function autonomously or essentially autonomously. Accordingly, aids such as supply lines to the exhaust gas burner for the combustion of the exhaust gas could be dispensed with. As a result, the exhaust gas burner can be provided in a particularly space-saving manner. Furthermore, the degree of complexity of the fuel cell system can be kept low. In the context of the present invention, it has proven to be particularly advantageous if the exhaust gas burner has, in addition to the exhaust gas burner catalyst, an electrical heating means for additionally heating the anode exhaust gas and / or the cathode exhaust gas. The exhaust gas burner can first be brought to a predefined operating temperature by means of the electrical heating medium, so that it can then function with the appropriate efficiency. In a preferred embodiment
    PP31438AT
    AVL List GmbH design variant, the exhaust gas burner catalytic converter can be designed as a coating of the electrical heating means. As a result, the exhaust gas burner can be made available in a particularly space-saving manner.
    In a fuel cell system according to the invention, it can furthermore be advantageous if the reformer for reforming the anode gas has a reformer catalytic converter, in particular a ring-shaped oxidation catalytic converter, which is arranged at least in sections around the exhaust gas burner section and / or the exhaust gas burner catalytic converter. With regard to the advantages of the reformer catalytic converter, what has been described above for the exhaust gas burner catalytic converter applies analogously. In a fuel cell system according to the invention, it is particularly advantageous if the annular reformer catalyst, which is arranged in the appropriately designed reformer, is positioned in a ring around the cylindrical exhaust gas burner catalyst, which is arranged in the appropriately designed exhaust burner, ie when the reformer Catalyst is arranged at least in sections coaxially with the exhaust gas burner catalyst. With such an arrangement, a particularly effective heat transfer between the corresponding sections of the exhaust gas burner and the reformer can be realized.
    In a further embodiment variant of the present invention, it is possible that, in a fuel cell system, the exhaust gas burner for the combustion of the anode exhaust gas and / or the cathode exhaust gas has an exhaust gas burner injector for injecting fuel into the exhaust gas burner. Using the exhaust burner injector, a fuel-air mixture in the exhaust burner can be quickly and easily adjusted to a desired stoichiometric mixing ratio. In particular, it is possible to inject fuel in a metered manner into the exhaust gas burner in order to temporarily increase a combustion temperature in the exhaust gas burner, for example during a starting process of the fuel cell system. In a fuel cell system according to the present invention, it is possible in a particularly simple manner to position the exhaust burner injector on the cylindrical exhaust burner.
    According to a further aspect of the present invention, a method for operating a fuel cell system as described in detail above is disclosed
    8/26
    PP31438AT
    AVL List GmbH
    Provided. A method according to the invention thus brings with it the same advantages as have been described in detail with reference to the fuel cell system according to the invention. As part of the method, a substoichiometric fuel-air mixture is burned in the start burner in a predefined time window during a start operation of the fuel cell system. This allows the exhaust gas burner to be heated efficiently.
    In addition, it is possible in a method according to the invention in the reformer to burn a substoichiometric fuel-air mixture in a predefined time window during a starting operation of the fuel cell system as part of a catalytic partial oxidation. As a result, heat is additionally fed to the reformer, as a result of which the reformer can be heated particularly effectively, particularly during the starting process of the fuel cell system. In addition, the anode can be protected against oxidation by air or oxygen by CPOX operation or by the catalytic partial oxidation in the reformer.
    According to a further aspect of the present invention, a motor vehicle with a fuel cell system as described in detail above for the energy supply of at least one drive unit of the motor vehicle is made available. A motor vehicle according to the invention thus also has the same advantages as have been described in detail above.
    Further measures improving the invention result from the following description of various exemplary embodiments of the invention, which are shown schematically in the figures. All of the features and / or advantages arising from the claims, the description or the drawing, including structural details and spatial arrangements, can be essential to the invention, both on their own and in the various combinations.

    Elements with the same function and mode of operation are given the same reference numerals in FIGS. 1 to 5.
    1 schematically shows a fuel cell system 100a according to a first embodiment. The fuel cell system 100a is configured in the form of an SOFC system and has a fuel source 13 in the form of a fuel tank and an oxygen source 14 in the form of a blower.
    The fuel cell system 100a further has a fuel cell stack 1 with an anode section 2 and a cathode section 3, a reformer 4 for supplying reformed anode gas to the anode section 2, and an exhaust gas burner 5 for burning anode exhaust gas from the anode section 2 and cathode exhaust gas from the cathode section 3. The reformer 4 is arranged in a ring around the exhaust gas burner 5, an inner wall section of the reformer 4 being arranged in full or at least substantially in full around an outer wall section of the exhaust gas burner 5 (will be explained in more detail with reference to FIG. 2).
    As shown in FIG. 1, an evaporator 6 for evaporating anode gas is arranged downstream of the exhaust gas burner 5 and upstream of the reformer 4. A heat exchanger 7 is arranged downstream of the evaporator 6, the heat exchanger 7 being arranged on the reformer 4 for heating the reformer 4 or anode gas in the reformer 4. According to the embodiment shown in Fig. 1
    10/26
    PP31438AT
    AVL List GmbH can thus convey exhaust gas from the exhaust burner 5 directly via the evaporator 6 to the heat exchanger 7, and from there into the surroundings of the fuel cell system 100a.
    Fuel or anode gas can be conveyed from the fuel source 13 via the evaporator 6 to the ring-shaped reformer 6 and from there to the anode section 2 as a reformed anode gas. Air or an oxygen-containing fluid can be conveyed from the oxygen source 14 via the heat exchanger 7 to the cathode section 3.
    2, the reformer 4, the exhaust gas burner 5 and the evaporator 6 are shown schematically according to a preferred embodiment. As can be seen in FIG. 2, the evaporator 6 is arranged directly downstream of the exhaust gas burner 5. It can further be seen from FIG. 2 that the reformer 4 has an annular reformer catalytic converter 12 which is arranged in a manner corresponding to a passage volume of the reformer 4 therein. It is also shown that the exhaust gas burner 5 has a cylindrical exhaust gas burner catalytic converter 11 in the form of an oxidation catalytic converter for burning the anode exhaust gas and the cathode exhaust gas, which catalytic converter is arranged corresponding to a passage volume of the exhaust gas burner 5 therein. The exhaust gas burner catalytic converter 11 and the reformer catalytic converter 12 are only separated from one another by a partition of the reformer 4 and the exhaust gas burner 5. The reformer catalytic converter 12 is arranged around the exhaust gas burner catalytic converter 11 over its entire length. As a result, particularly good heat transport from the exhaust gas burner 5 or from the exhaust gas burner catalytic converter 11 to the reformer 4 or the reformer catalytic converter 12 can be achieved.
    A fuel cell system 100b according to a second embodiment is described below with reference to FIG. 3. The fuel cell system 100b according to the second embodiment essentially corresponds to the fuel cell system 100a according to the first embodiment. To avoid redundant description, only the distinguishing features according to the second embodiment are described below.
    11/26
    PP31438AT
    AVL List GmbH
    In the fuel cell system 100b shown in FIG. 3, the exhaust gas burner 5 for the combustion of the anode exhaust gas and the cathode exhaust gas has an exhaust gas burner injector 10 for injecting fuel into the exhaust gas burner 5.
    A fuel cell system 100c according to a third embodiment is described below with reference to FIG. 4. The fuel cell system 100c according to the third embodiment essentially corresponds to the fuel cell system 100a according to the first embodiment and the fuel cell system 100b according to the second embodiment. In order to avoid a redundant description, only the distinguishing features according to the third embodiment are described below.
    In the fuel cell system 100c shown in FIG. 4, a start burner 8 for heating cathode exhaust gas and anode exhaust gas, which flows in the direction of the exhaust gas burner 5, is arranged upstream of the exhaust gas burner 5. The starting burner 8 has a starting burner injector 9 for injecting fuel into the starting burner 8. The start burner 8 or the start burner injector 9 can be supplied with fuel from the fuel source 13 and with oxygen from the oxygen source 14. For a metered supply of oxygen from the oxygen source 14 to the start burner 8, a metering valve 15 is arranged in an oxygen line upstream of the start burner 8 and downstream of the oxygen source 14.
    A method for operating the illustrated fuel cell system 100c during a starting process of the fuel cell system 100c is subsequently described with reference to FIG. 4.
    When the fuel cell system is started, fuel is supplied to the starting burner 8 from the fuel source 13 and an oxygen-containing fluid, in particular air, from the oxygen source 14. As a result, a corresponding fuel-air mixture can be burned in the starting burner 8 for heating the exhaust gas burner 5. During the starter operation of the fuel cell system, a substoichiometric fuel-air mixture is burned in the start burner 8. In a predefined time window during the starting operation of the fuel cell system 100c, a substoichiometric fuel-air mixture is also burned in the reformer 4 as part of a catalytic partial oxidation. Here the temperature

    Reformer 4, on the exhaust gas burner 5 and / or on the fuel cell stack 1 is above a predefined threshold value, the start burner 8 is deactivated. That is, supply of fuel and oxygen is stopped.
