PURPOSE:To constitute a highly efficient molten-carbonate-type fuel cell generation system by effectually utilizing thermal energy or high quality by using a solid-electrolyte-type fuel cell instead of a fuel reformer. CONSTITUTION:A fuel 80 is supplied to a solid-electrolyte-type fuel cell 72 through a preheater 71 and the pressure of air 81 is increased by a compressor 77 before the air 81 is supplied to the fuel cell 72 through a preheater 73 to produce electric output 83a. Discharged fuel 80b from the fuel cell 72 is heated by the preheater 71 before the pressure of the fuel 80b is increased by a compressor 76 and then the preheated compressed fuel 80b is supplied to the fuel electrode 75d of a molten-carbonate-type fuel cell 75. At the same time, discharged air 81b from the fuel cell 72 is heated by the preheater 73 before the air 81b and the discharged fuel from the fuel cell 75 are burned in a catalyst combuster 74 to produce air and carbon dioxide gas which are then supplied to the air electrode 75e of the fuel cell 75, thereby producing an electric output 83b. Consequently, the structure of the fuel cell generation system can be simplified without using any fuel reformer or an auxiliary system. Furthermore, the efficiency of the system can be improved by effectually utilizing thermal energy. |
