POWER GENERATOR INCLUDING FUEL BATTERY AND GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a power generator capable of operating both a fuel battery and a gas turbine at appropriate temperatures.SOLUTION: A power generator 100 comprises: a compressor C compressing air; a first heat exchanger R1 heating the air compressed by the compressor C; a fuel battery 17 having an air electrode Ca to which the air heated by the first heat exchanger R1 is supplied and a fuel electrode An to which fuel is supplied, and generating electric power by causing a reaction between oxygen in the air and the fuel; a second heat exchanger R2 heating exhaust air from the air electrode Ca; a combustion chamber CC mixing up and burning the exhaust air heated by the second heat exchanger R2 and exhaust gas from the fuel electrode An; and a turbine T driven by the combustion gas from the combustion chamber CC. The exhaust gas from the turbine T is supplied to the second heat exchanger R2 to heat the exhaust air from the air electrode Ca, and then supplied to the first heat exchanger R1 to heat the air compressed by the compressor C.
