[0020] Hereinafter, embodiments of a fuel cell module to which the present invention is applied will be described with reference to the drawings.
[0021] like Figure 1 As shown, a fuel cell device 11 including a fuel cell module 10 according to an embodiment of the present invention is configured to include the fuel cell module 10, a first heat exchanger 12, a second heat exchanger 13, and a storage unit 14. The fuel cell device 11 may be configured to further include a third heat exchanger 15, a radiator 16, a first supply path 17, and a second supply path 18.
[0022] The fuel cell module 10 includes a container 19 , a fuel cell 20 , a combustion unit 21 , and a first reactor 22 . The fuel cell module 10 may further include a second reactor 23 .
[0023] The container 19 accommodates the fuel cell 20, the combustion unit 21, and the first reactor 22. The container 19 may accommodate the second reactor 23.
[0024] The fuel cell 20 may be a single cell stack formed by stacking fuel cell monomers. The fuel cell 20 may include a plurality of single cell stacks. The fuel cell monomer is, for example, a solid oxide fuel cell (SOFC), which generates electricity by an electrochemical reaction using an oxygen-containing gas contained in the air and a fuel such as hydrogen sent from the first reactor 22 as described later. In addition, the fuel cell 20 generates water through an electrochemical reaction. The fuel cell 20 discharges an exhaust gas containing at least unreacted fuel, unreacted oxygen, and water vapor. The fuel cell 20 operates at a high temperature of more than 700° C. in an SOFC, for example, so the exhaust gas is also high temperature. The exhaust gas of the fuel cell 20 is supplied to the combustion unit 21 via an exhaust gas flow path.
[0025] The combustion unit 21 burns the unreacted fuel contained in the exhaust gas supplied from the fuel cell 20. The combustion unit 21 burns the unreacted fuel using, for example, an oxidant that has not reacted in the fuel cell 20. The combustion unit 21 may have, for example, a plurality of gas outlets. The plurality of gas outlets may be arranged in a dispersed manner on a plane. Alternatively, the plurality of gas outlets may be arranged in a dispersed manner on the inner circumferential surface of a cylinder.
[0026] The combustion unit 21 may be arranged side by side with the fuel cell 20 in a direction perpendicular to or parallel to the stacking direction of the fuel cell monomers constituting the fuel cell 20. In the structure where the combustion unit 21 is arranged side by side with the fuel cell 20, a plurality of gas outlets may be provided to be dispersed along the stacking direction.
[0027] The first reactor 22 is disposed opposite to the combustion unit 21. Figure 2 As shown in FIG. 1 , the first reactor 22 may be disposed opposite to the combustion section 21 in which the plurality of gas outlets are dispersedly arranged on a plane, and the surface 24 in which the gas outlets are disposed may be disposed. Figure 3 As shown, in a structure in which a plurality of gas blowing outlets are dispersedly arranged on the inner peripheral surface 25 of the cylinder, the first reactor 22 can be provided so as to face the inner peripheral surface 25 .
[0028] like Figure 2 , 3 As shown in the figure, an organic hydride can be supplied to the first reactor 22 as described later. The organic hydride is, for example, an organic compound that can reversibly release hydrogen, such as methylcyclohexane, cyclohexane, decalin, etc. The first reactor 22 generates at least hydrogen and dehydrogenated products from the organic hydride through a dehydrogenation reaction. A raw fuel gas containing hydrogen, dehydrogenated products, and unreacted organic hydride can be sent out from the first reactor 22. At least a portion of the hydrogen contained in the raw fuel gas is supplied to the fuel cell 20 as a fuel as described later.
[0029] The first reactor 22 may include a first gasification section 26 and a dehydrogenation section 27. The first gasification section 26 and the dehydrogenation section 27 may be separated by, for example, an inner wall in the first reactor 22. The first gasification section 26 and the dehydrogenation section 27 may be connected. The first reactor 22 may be disposed in the fuel cell module 10 in such a manner that the dehydrogenation section 27 is located downstream of the first gasification section 26.
[0030] The first vaporization section 26 can vaporize the organic hydride. The first vaporization section 26 can be filled with a filler to promote vaporization. The dehydrogenation section 27 can accommodate a dehydrogenation catalyst. The dehydrogenation section 27 can cause the organic hydride vaporized in the first vaporization section 26 to undergo a dehydrogenation reaction.
[0031] The second reactor 23 may be located between the first reactor 22 and the combustion unit 21. The second reactor 23 may be supplied with the separation gas and water generated by combustion in the combustion unit 21. As described later, the separation gas may be sent from the first reactor 22 and contain hydrogen and an organic compound supplied together with the hydrogen.
[0032] The second reactor 23 generates hydrogen and carbon dioxide from the organic compound by, for example, a steam reforming reaction. It should be noted that the hydrogen supplied to the second reactor 23 can be sent out as it is. Hydrogen, carbon dioxide, and unreacted water vapor can be sent out from the second reactor 23. The fuel gas generated by the second reactor 23 is supplied to the fuel cell 20.
[0033] The second reactor 23 may have a second gasification section 28 and a reforming section 29. The second gasification section 28 and the reforming section 29 may be separated by, for example, an inner wall in the second reactor 23. The second gasification section 28 and the reforming section 29 may be connected. The second reactor 23 may be arranged in the fuel cell module 10 in such a way that the reforming section 29 is located downstream of the second gasification section 28. In the fuel cell module 10, the second gasification section 28 may be arranged separately from the first gasification section 26. Specifically, the first gasification section 26 and the second gasification section 28 may be arranged separately when viewed from the side-by-side direction in which the first reactor 22 and the second reactor 23 are arranged side by side. More specifically, the first gasification section 26 may be arranged at an end of one side of the side-by-side direction, and the second gasification section 28 may be arranged at an end of the other side.
[0034] The second vaporization unit 28 can vaporize water. The second vaporization unit 28 can be filled with a filler to promote vaporization. The reforming unit 29 can accommodate a reforming catalyst. The reforming unit 29 can use the water vaporized in the second vaporization unit 28 to cause a reforming reaction of the organic compound.
[0035] The combustion unit 21, the first reactor 22, and the second reactor 23 can be installed at any position and in any posture in the container 19. The combustion unit 21, the first reactor 22, and the second reactor 23 can be installed, for example, vertically above the fuel cell 20 in the correct installation posture for the fuel cell device 11. Alternatively, the combustion unit 21, the first reactor 22, and the second reactor 23 can be installed, for example, on the side of the fuel cell 20 in the correct installation posture of the fuel cell device 11. A partition wall can be provided between the combustion unit 21 and the fuel cell 20.
[0036] like Figure 1 As shown, the first heat exchanger 12 can perform heat exchange between the raw fuel gas sent from the first reactor 22 and the oxygen-containing gas supplied to the fuel cell 20. It can be that the raw fuel gas sent from the first reactor 22 is cooled by heat exchange with the oxygen-containing gas, thereby liquefying the components with lower boiling points in the raw fuel gas. The components with lower boiling points in the raw fuel gas can be dehydrogenated products and organic hydrides. The oxygen-containing gas can be sent to the first heat exchanger 12 by boosting the pressure using a blower, etc. The oxygen-containing gas can be heated by heat exchange and supplied to the fuel cell 20.
[0037] The second heat exchanger 13 can perform heat exchange between the raw fuel gas and the heat medium that have been heat exchanged in the first heat exchanger 12. The liquefied component can be supplied to the second heat exchanger 13 together with the raw fuel gas. The heat medium can be a liquid. The heat medium can be water. The raw fuel gas sent out from the first heat exchanger 12 can be further cooled by heat exchange with the heat medium, thereby further liquefying the component with a lower boiling point.
[0038] The storage unit 14 can be connected to the first reactor 22 via the first heat exchanger 12 and the second heat exchanger 13. The storage unit 14 can store dehydrogenated products contained in the raw fuel gas. The storage unit 14 can store organic hydrides contained in the raw fuel gas. The storage unit 14 can, for example, separate and store dehydrogenated products and organic hydrides liquefied by heat exchange in the first heat exchanger 12 and the second heat exchanger 13 from hydrogen. The liquefied dehydrogenated products and organic hydrides can be separated from hydrogen, for example, by the first gas-liquid separator 30 disposed between the second heat exchanger 13 and the storage unit 14. The first gas-liquid separator 30 can supply the separated gas having the hydrogen separated from the raw fuel gas as a main component to the second reactor 23. The separated gas can contain gaseous dehydrogenated products and organic hydrides that are not liquefied as the above-mentioned organic compounds.
[0039] The third heat exchanger 15 can perform heat exchange between the exhaust gas discharged from the fuel cell module 10 and the heat medium that has undergone heat exchange in the second heat exchanger 13. Specifically, the exhaust gas discharged from the fuel cell module 10 can be the exhaust gas obtained by combustion in the combustion unit 21. The exhaust gas can contain carbon dioxide, oxygen, water vapor, nitrogen, etc. The exhaust gas of the fuel cell module 10 can be cooled by heat exchange with the heat medium, thereby liquefying the water vapor in the exhaust gas.
[0040] The water liquefied by heat exchange in the third heat exchanger 15 can be separated from the exhaust gas by the second gas-liquid separator 31. The separated water can be stored in the reforming water tank 32. The water stored in the reforming water tank 32 can be pressurized by the pump 33 and supplied to the second reactor 23.
[0041] The radiator 16 can cool the heat medium that has exchanged heat in the third heat exchanger 15. The radiator 16 can circulate the cooled heat medium to the second heat exchanger 13. The radiator 16 is, for example, a radiator. Heat can be recovered from the heat medium that has exchanged heat in the third heat exchanger 15 and used.
[0042] The first reactor 22 may be switchably connected to the first supply path 17 and the second supply path 18. For example, the first reactor 22 may be connected to the first supply path 17 and the second supply path 18 via a three-way valve 34. The organic hydride may be supplied to the first supply path 17 from outside the fuel cell device 11. The first fuel may be supplied to the second supply path 18 from outside the fuel cell device 11. The first fuel may be a substance that can be used as a fuel for the fuel cell 20. The first fuel is, for example, hydrogen.
[0043] The fuel cell module 10 of the present embodiment having the above-described structure includes: a combustion section 21 that burns unreacted fuel in the fuel cell 20, the unreacted fuel being supplied to the combustion section 21 via a flow path of exhaust gas containing the unreacted fuel; and a first reactor 22 that is opposed to the combustion section 21 and generates at least hydrogen and dehydrogenated products from organic hydrides by a dehydrogenation reaction, and at least a portion of the hydrogen generated by the first reactor 22 is supplied to the fuel cell 20 as fuel. With such a structure, the fuel cell module 10 can utilize the high-temperature heat used for the operation of the fuel cell 20 for the endothermic reaction of the organic hydrides, and utilize the high-temperature heat generated by the combustion of the unreacted fuel for the endothermic reaction of the organic hydrides. Therefore, the fuel cell module 10 can stably generate electricity even if the heat used for the operation of the fuel cell 20 varies according to the amount of power generation, by a relatively simple structure such as the combustion section 21.
[0044] In addition, the fuel cell module 10 has a second reactor 23, which is located between the first reactor 22 and the combustion unit 21, and reforms the organic compound sent out from the first reactor 22 and supplied together with hydrogen. The hydrogen contained in the raw fuel gas sent out from the first reactor 22 is separated from the organic compounds such as dehydrogenates and organic hydrides using the first gas-liquid separator 30, etc., but it is difficult to separate them completely. Therefore, usually a part of the organic compound is sent to the supply path of the fuel cell 20 together with the hydrogen. In response to such a phenomenon, the fuel cell module 10 having the above-mentioned structure reforms the mixed organic compound into hydrogen, thereby reducing the impact caused by the organic compound being supplied to the fuel cell 20.
[0045] In addition, in the fuel cell module 10, the second gasification section 28 constituting the second reactor 23 is configured separately from the first gasification section 26 constituting the first reactor 22. In either the first reactor 22 or the second reactor 23, the gasification of the organic hydride and water at room temperature absorbs more heat than the dehydrogenation reaction and reforming reaction in the subsequent stage. Therefore, the temperature drop in the vicinity of the first gasification section 26 and the second gasification section 28 is large. In response to such a phenomenon, the fuel cell module 10 having the above-mentioned structure can make the temperature distribution in the first reactor 22 and the second reactor 23 uniform as a whole. The fuel cell module 10 can contribute to the uniformity of the temperature distribution of the fuel cell monomers constituting the fuel cell 20 by making the temperature distribution uniform, for example.
[0046] In addition, the fuel cell device 11 of the present embodiment includes: a fuel cell module 10; and a storage unit 14, which is connected to the first reactor 22 via the first heat exchanger 12 and the second heat exchanger 13, and stores dehydrogenated products. With such a structure, the fuel cell device 11 can recover the dehydrogenated products used for the storage and transportation of hydrogen and use them as raw materials for hydrogenation at the hydrogen supply site.
[0047] In addition, in the fuel cell device 11 of the present embodiment, the first heat exchanger 12 performs heat exchange between the raw fuel gas sent from the first reactor 22 and the oxygen-containing gas supplied to the fuel cell 20. The higher the temperature of the oxygen-containing gas supplied to the fuel cell 20, the higher the power generation efficiency. In view of such a phenomenon, the fuel cell device 11 having the above-mentioned structure can effectively utilize the heat of the raw fuel gas that needs to be cooled.
[0048] In the fuel cell device 11 of this embodiment, the second heat exchanger 13 performs heat exchange between the raw fuel gas and the heat medium that have undergone heat exchange in the first heat exchanger 12. With such a structure, the fuel cell device 11 can further cool the raw fuel gas and thereby increase the amount of dehydrogenated products recovered.
[0049] In addition, the fuel cell device 11 of the present embodiment includes a third heat exchanger 15, which performs heat exchange between the exhaust gas discharged from the fuel cell module 10 and the heat medium that has undergone heat exchange in the second heat exchanger 13. With such a structure, the fuel cell device 11 uses the supply path of the heat medium for recovering reforming water from the exhaust gas and the supply path of the heat medium for cooling the raw fuel gas, thereby simplifying the structure.
[0050] The fuel cell device 11 of this embodiment includes a radiator 16 that cools the heat medium that has exchanged heat in the third heat exchanger 15 and circulates it to the second heat exchanger 13. With such a configuration, the fuel cell device 11 can sufficiently cool the heat medium and maintain the recovery amounts of dehydrogenated products and reforming water.
[0051] In addition, the fuel cell device 11 of the present embodiment is switchably connected to the first reactor 22 with the first supply path 17 for supplying the organic hydride and the second supply path 18 for supplying the first fuel. During the period from the start of the operation of the fuel cell 20 to the start of power generation, the temperature around the fuel cell 20 is low and sufficient heat for dehydrogenation may not be generated. In view of such a phenomenon, the fuel cell device 11 having the above-mentioned structure can directly supply the first fuel to the fuel cell 20 via the second supply path 18. Therefore, the fuel cell device 11 can start the supply of the first fuel to the fuel cell 20 even at a relatively low temperature.
