PURPOSE:To obtain a fused-salt type fuel cell power generating plant, which can improve the characteristic of a fuel cell main body itself and which can maintain the output characteristic of the power generating plant high for a long term stably. CONSTITUTION:Fuel gas is supplied to an anode through a pipeline 4, and air is supplied to a cathode of a fuel cell main body 2 through a pipeline 8. Supply rate of the reaction gas is controlled at a predetermined flow rate on the basis of the power generating condition such as a load current rate and reaction gas utilization rate. The gas of a cathode outlet of the fuel cell main body 2 is led into a discharged heat recovering device 10 through a pipeline 9, and heat exchange is performed between this gas and the water supplied to the discharged heat recovering device 10 so as to generate the steam, and thereafter, the gas is discharged out of a system through a pipeline 11. In a real plant, a part of the gas of the cathode outlet is used as the cycle gas for cooling the fuel cell main body 2 from a compressor, and generally, a part of the gas is led into a turbine compressor and used for compressing the air and used as a gas source for turbine power generation. |
