PURPOSE: To improve an efficiency and prevent generation of harmful exhaust material by using gaseous fluid exhausted from a compressor turbine by comparatively low pressure and a temperature as oxidizing agent in a fuel cell together with reducer such as natural gas and the like. CONSTITUTION: Air 1 is heated with exhaust gas from a gas turbine 6 by a flame pipe gas exchanger I through a compressor unit 2, and a compressor turbine 4 is driven. After that, a temperature is reduced while releasing energy, and it flows to a negative electrode Ca side of a fuel cell 10 as oxidizing agent. Fuel such as natural gas is supplied to a positive electrode An of the fuel cell 10 through a heat exchanger V as reducer so as to generate electric energy. Burnt fuel and air are filled into a gas turbine 6, a power generator 14 is driven, and power is generated. After that, they are supplied to the heat exchanger I, and air compressed by a compression unit 2 is heated. It is thus possible to improve a heat efficiency and exhaust gas property. |
