ABSTRACT:
A power generation system uses fuel cells stacked via separators. Cooling plates are provided in the fuel cell stack. Passages are formed in each cooling plate for allowing raw-material-gas-for-reformation (which also serves as stack-cooling-gas) to flow therethrough and the passages are filled with reforming catalyst. An external reformer which includes a combustion section and a reforming section is provided outside of the fuel cell stack. A stack-cooling-gas-line is connected to the passages of the cooling plates for introducing the raw-material-gas-for-the-reformation (the stack-cooling-gas) into the passages. A line for gas-for-processing is connected to the reforming section of the external reformer for feeding raw-material-gas-for-processing to the reforming section. An anode gas feed line is provided for feeding to the anode the reformed gas which has been reformed through the passages of the cooling plates and the reformed gas which has been reformed by the reforming section of the external reformer. An anode exit gas line is provided for feeding the anode exit gas to the combustion section of the external reformer. A cathode gas feed line is provided for feeding the combustion exhaust gas discharged from the combustion section to the cathode with air. A cathode exit gas line is provided for discharging the cathode exit gas.
