    Exhaust aftertreatment device with reformer and burner for a SOFC system
    The present invention relates to an exhaust aftertreatment device for a
    A fuel cell system, in particular for a SOFC system, for treating a fuel for a fuel cell stack of the fuel cell system, wherein the exhaust aftertreatment unit comprises a reformer for supplying reformed Anodenzuführgas to the anode section and a ring around the reformer disposed exhaust gas burner for burning fuel gas from the fuel cell stack. The invention further relates to a fuel cell system having an exhaust aftertreatment device as described above and a motor vehicle having the fuel cell system.
    From AT 513 932 A1, a catalyst unit for a high temperature is used
    Fuel cell system or an SOFC system with a reforming catalyst of a reformer for the preparation of a fuel for a fuel cell and an oxidation catalyst of an exhaust gas burner for the exhaust aftertreatment of the fuel cell fuel forth. According to AT 513 932 A1, the oxidation catalyst is arranged annularly around the cylindrically designed reforming catalyst. The gas paths of the oxidation catalyst and the reforming catalyst are separated by a metal reactor containing the refractory metal tube, wherein the metal tube has a sleeve which forms a housing for the reforming catalyst, and an inner tube which forms the inner wall of the annular oxidation catalyst. By such an arrangement, a particularly effective heat transfer between the reforming catalyst and the oxidation catalyst or between the reformer and the exhaust gas burner can be realized in a compact manner. For an additional heating of the oxidation catalyst, a starting burner is arranged in the fuel cell system, which can additionally heat or preheat the oxidation catalyst, in particular during a start operation of the fuel cell system. It is desirable, especially for mobile purposes, the number of components and thus to keep the size and weight of a fuel cell system as small as possible or low.
    Object of the present invention is to at least partially take into account the prob lematics described above. In particular, it is an object of the present invention to provide a compact, lightweight and simply constructed
    Exhaust after-treatment device for use in a Brennstoffzellensys system of the type mentioned above to provide.
    The above object is solved by the claims. In particular, the above object is achieved by the exhaust gas aftertreatment device according to claim 1, the fuel cell system according to claim 11 and the motor vehicle according to claim 12. Further advantages of the invention will become apparent from the dependent claims, the description and the drawings. In this case apply
    Features and details that are described in connection with the Abgasnachbehandlungsvor direction, of course, also in connection with the inventive fuel cell system, the motor vehicle and in each case vice versa, so with respect to the disclosure of the individual aspects of the invention is always reciprocal reference or can be.
    According to a first aspect of the present invention, there is provided an exhaust gas post-treatment apparatus for a fuel cell system having a fuel cell stack having an anode portion and a cathode portion. The exhaust aftertreatment device includes a reformer for supplying reformed anode supply gas to the anode section and an exhaust burner for burning fuel gas from the fuel cell stack, wherein the exhaust gas burner is at least partially annularly arranged around the reformer. The exhaust aftertreatment device further includes a fuel gas
    Line section for supplying the fuel gas to the exhaust gas burner. The gas burner has an exhaust gas burner oxidation catalyst for burning
    Fuel gas, which is passed from the fuel cell stack to the exhaust gas burner on. In addition, a heating means for preheating the fuel gas or optionally introduced fuel is arranged in the fuel gas line section.
    In the context of the present disclosure, fuel gas is understood to mean anode and cathode exhaust gas, oxygen or an oxygen-containing gas, in particular air or ambient air with injected fuel, each by itself or in mixtures with one another.
    By arranged in the fuel gas line section heating means, the exhaust gas burner oxidation catalyst can be preheated efficiently at system startup and insbesonde re with liquid or gaseous hydrocarbons are used as fuels. At system startup, liquid fuel is used in particular. Accordingly, the heating means is configured for preheating the fuel gas and / or the particular fuel used before it encounters the exhaust gas oxidation catalyst. Accordingly, the heating means is arranged in a fuel gas flow direction upstream of the exhaust gas burner oxidation catalyst. The preheating method makes it possible to integrate in the exhaust gas burner starting burner and afterburner functionalities in a component or form as a common component. For a particularly effective preheating effect, the heating means is preferably arranged directly in front of or at the exhaust gas burner oxidation catalytic converter. As a result, the fuel gas heated by the heating medium can enter the exhaust gas burner oxidation catalytic converter without or substantially without further thermal interactions with the surroundings from the heating medium.
    By the arrangement of the heating medium in the vicinity of the exhaust gas burner
    Oxidation catalyst, the present exhaust aftertreatment device can be provided particularly compact. Preferably, the reformer and the exhaust gas burner are arranged in a common housing or surrounded by this housing substantially, at least in sections. Within this housing, the fuel gas line section may be configured in which the heating means is located. Such a design variant can be realized correspondingly compact. In addition, in the fuel gas piping section, the exhaust gas burner is preferably arranged with respect to a fuel gas flow direction corresponding to the downstream of the heating medium.
    The exhaust aftertreatment device is particularly designed for use in a SOFC system. For reforming the fuel supplied to the anode section, the reformer preferably has a reforming catalyst by means of which the fuel required at the anode section can be reformed or generated. Since the reforming taking place in the reformer is endothermic, a heat input from the exhaust gas burner, in which an exothermic reaction takes place when burning the fuel gas, is of crucial importance. Due to the present construction, in which the exhaust gas burner is arranged in an annular manner around the reformer, heat transfer from the exhaust gas burner to the reformer can be realized in a particularly effective manner.
    The fuel gas conduit section can form part of an anode exhaust gas line and / or cathode exhaust gas line or can be designed as a connection piece for supplying the anode exhaust gas and / or cathode exhaust gas in normal operation from the fuel cell stack to the exhaust gas burner. Accordingly, in an associated fuel cell system, the housing described above may be in fluid communication with the cathode portion and / or the anode portion through the fuel gas conduit portion, which in normal operation connects to exhaust passages of anode and cathode portions located outside or at least substantially outside of the housing stand. The cathode exhaust gas comprises predominantly air, whereas the anode exhaust gas also contains (unreacted) fuel. The fuel gas is a mixture of cathode exhaust gas and anode exhaust gas, the mixture is burned; In Nor malbetrieb exhaust is used as fuel gas; if necessary, air (ambient) and additional fuel can also be added. As Brennstoffzellensta pel the stack module is understood, which has a cathode portion and a
    Anode section includes.
    Under the heating means may be understood a one-part or multi-part component, wherein at least the main component of the heating medium in the fuel gas
    Line section is located. That is, the heating means is at least partially disposed in the fuel gas conduit section in which, in particular, a mixture of cathode exhaust gas and anode exhaust gas flows. Line sections which are required for heating a heating element of the heating means do not have to be arranged, for example, or at least not completely in the anode exhaust gas and / or cathode exhaust line section.
    The exhaust gas burner is arranged at least in sections, in particular around a central axis, coaxially with the reformer.
    According to one embodiment of the present invention, it is possible that the
    Heating means in an exhaust aftertreatment device comprises an electrical, in particular plate-shaped, heating means. With the help of an electric heating medium, the fuel gas can be heated particularly easily and efficiently. In addition, an elec- cal heating means can be placed to save space in the exhaust aftertreatment device. Electric heating means can also be provided relatively inexpensively. A plate-shaped heating means is to be understood as meaning a heating means which, compared with a height of the heating means, has a length which is several times greater and also several times greater. The height of the heating means preferably extends in an exhaust gas flow direction (or fuel gas flow direction) and / or in a direction along the above-described central axis, around which the reformer and the exhaust gas burner are at least partially coaxial, possibly at least partially rotationally symmetrical are. Such an arrangement and design of the heating means, this is particularly platzspa end arranged in the fuel gas line section. The plate shape of the heating means is not limited to a specific geometric shape. A plate-shaped heating medium may also have one or more through holes.
    Furthermore, it is possible for the heating means to have a heating medium oxidation catalytic converter in an exhaust gas aftertreatment device according to the invention. Using a catalyst, the heating means can basically operate autonomously or essentially autonomously. Accordingly, could be dispensed with aids such as supply lines to the heating means. As a result, the heating means can be provided in a particularly space-saving manner. Furthermore, the degree of complexity of the
    Keep exhaust aftertreatment device low. In the context of the present invention it has been found to be particularly advantageous if the heating means so well the electric heating means and the heating medium oxidation catalyst has. By means of the electrical heating means (or the fuel gas burned or preheated by means of the latter), the heating-agent oxidation catalyst can first be brought to a predefined operating temperature, in order then to be able to function with corresponding efficiency. The heating medium oxidation catalyst may be configured as a coating of the electrical heating means.
    Moreover, it is possible that the heating means in a Abgasnachbehand treatment device according to the present invention is arranged coaxially with the exhaust gas burner or substantially coaxially with the exhaust gas burner. Due to the coaxial arrangement, the heating means can be particularly space-saving positioned on the exhaust gas burner. By such an arrangement, the heating means is also arranged flow favorable in the fuel gas line section. Accordingly, flow turbulence in the fuel gas can be avoided or at least reduced in such a configuration.
    It may be of further advantage if the heating means is configured disc-shaped in an exhaust gas treatment device and an outer circumference of the heating element is corresponded to an inner circumferential section of the fuel gas line section. This allows the available space in the exhaust aftertreatment device effectively use. The heating means preferably has the same or substantially the same diameter as the exhaust gas burner. Specifically, the exhaust gas burner and the heating means are arranged in a portion of the fuel gas piping section in which the inner diameter of the fuel gas piping section stays the same or substantially the same from the position of the heating means to the position of the exhaust gas burner. As a result, a compact and easy to handle overall system can be created.
    In the context of the present invention, it is also possible that the heating means in an exhaust aftertreatment unit designed annular and at least from section to the reformer around, in particular directly or substantially directly on the oxidation catalyst is arranged. As a result, the compactness of the exhaust aftertreatment unit can be further improved. The fuel gas
    Line section preferably extends at least partially annularly around the reformer. Characterized in that the heating means can be pushed in an annular configuration basically like the exhaust gas burner on the reformer, no space for the heating medium must be created in the fuel gas line section before the reformer. In addition, the proposed measure can increase the stability of the reformer-waste gas burner composite.
    In a further embodiment variant of the present invention, it can by
    Be advantageous if in an exhaust aftertreatment device at least one
    Fuel injector for injecting fuel into the fuel gas
    Line section, in particular in the direction of the heating means or in the flow Rich tion of the fuel gas, is arranged. The injected fuel can over the
    Heating means are promoted to the exhaust gas burner, which can be operated even more effective. If the heating means the electric heater or the heating means
    Having oxidation catalyst, can be due to the injected fuel in the fuel gas line section and the exhaust gas burner accordingly effectively
    Run system start - the exhaust gas burner acts as the starting burner for the system. In experiments within the scope of the present invention, it has been found that despite the increased financial and structural expense of the fuel injector for the entire system, that is, the exhaust aftertreatment device, it is profitable to provide the fuel injector of the invention for injecting the fuel into the fuel gas conduit section.
    It may be of particular advantage if, in an exhaust aftertreatment device according to the present invention, the at least one fuel injector is arranged coaxially with the heating means. A longitudinal axis of the fuel injector thus extends parallel to or coincident with a longitudinal axis of the heating medium. According to a variant of the invention, a longitudinal axis of the fuel injector is preferably arranged parallel to a fuel gas flow direction. As a result, the fuel can be injected into the fuel gas line section in a targeted and uniform manner in the direction of the heating means and of the exhaust gas burner. An injection direction of the at least one fuel injector runs correspondingly along a fuel gas flow direction. The at least one fuel injector is arranged in the fuel gas flow direction through the fuel gas conduit section upstream of the heating means spaced therefrom.
    Further, in an exhaust aftertreatment device according to the present invention, it is possible that two fuel injectors for injecting fuel are disposed in the fuel gas passage portion, and an injection direction of the fuel injectors is respectively transverse to a fuel gas flow direction. As a result, the fuel injected into the fuel gas conduit section can be effectively mixed with the exhaust gas or fuel gas. Even otherwise, the fuel can be well distributed in the fuel gas line section. Accordingly advantageously, the heating means and the exhaust gas burner can be wetted with the fuel. This in turn leads to a correspondingly effective combustion, both on a heating means with heating medium oxidation catalyst and the exhaust gas burner. In experiments within the scope of the present invention, it has surprisingly been found that these advantages outweigh the disadvantages which the two fuel injectors could pose in terms of system complexity, weight and cost.
    Moreover, in an exhaust aftertreatment device according to the present invention, it is possible that a cooling fluid passage for cooling the at least one fuel injector is disposed on the at least one fuel injector, the cooling fluid passage being part of an oxygen supply passage for supplying oxygen into the fuel gas passage section for combustion with fuel. which is injected by the at least one fuel injector into the fuel gas conduit section, and wherein the cooling fluid conduit is disposed upstream of an end portion of the oxygen supply conduit which opens into the fuel gas conduit section. Accordingly, oxygen or an oxygen-containing fluid, which is supplied to the fuel gas line section for better combustion at the exhaust gas burner and / or the heating means, can be additionally used as cooling fluid for cooling the we least one fuel injector. This allows the exhaust aftertreatment device operate particularly efficient. By cooling the at least one fuel injector, it can be protected from overheating by the temperatures occurring in the fuel gas line section. This contributes to the safe operation of the exhaust aftertreatment device.
    According to a further aspect of the present invention, a fuel cell system, in particular a SOFC system, is provided which has a
    Fuel cell stack having an anode portion and a cathode portion. The fuel cell system further includes an exhaust aftertreatment device as described in detail above, wherein the reformer is provided with the
    Anode section for supplying reformed Anodenzuführgas to the anode section is in fluid communication and the exhaust gas burner is in fluid communication with the anode and cathode section for burning fuel gas. Thus, a fuel cell system according to the invention brings about the same advantages as have been described in detail with reference to the exhaust aftertreatment device according to the invention.
    Furthermore, in the context of the present invention, a motor vehicle with a fuel cell system as described above is proposed. The fuel cell system is therefore designed for mobile use. In addition, a motor vehicle according to the invention thus also brings with it the advantages, as they have been described in detail in the present case.
