| 摘要 |
The invention provides a fuel cell system with stacked fuel cells arranged in a fuel cell block, with an inlet for fresh combustion gas at the anodes on one side of fuel cell block and an outlet for the used combustion gas on the opposite side, as well as inlet for fresh cathode gas at the cathodes on another side of fuel cell block and an outlet for used cathode gas on the opposite side. A reforming device, which utilizes heat given off in the fuel cell reaction to reform the fresh combustion gas fed to the anode inlet of fuel cells, has an area provided with a catalyst. An inlet to the catalyst area receives fresh combustion gas to be reformed, which passes through the area containing the catalyst, in which the reforming process takes place, and exits through an outlet. The reforming device is designed as a heat exchanger located in the exhaust gas stream directly behind the fuel cell block. Exhaust gas from the fuel cells is guided through the heat exchanger as a heating gas for heating the reforming device. |
