Using fuel and air introduced for working a power generation portion 20, cooling of the power generation portion 20 is performed in a reaction gas heat exchanger 24. This obviates the necessity for separately introducing air for cooling, and only compressed air necessary for working is introduced. Thus, the power of an air pressure feed source for a fuel cell apparatus is cut down, and a power generation output relative to the amount of air is increased. Consequently, the electric output/efficiency of the fuel cell apparatus and the output/efficiency of power generation equipment are increased.
