PROBLEM TO BE SOLVED: To improve a power generation output efficiencies of a fuel cell device and an electric generator by disusing separate cooling air but cooling the fuel cell device only by compressed air necessary for operation. SOLUTION: A power generation part 20 is cooled at a reaction gas heat exchanger 24 by the fuel and air introduced for the operation of the power generation part 20. Introduction of separate cooling air is disused and only compressed air necessary for the operation is introduced, consequently, power generation ratio against the volume of air is heightened by reducing a motive force of a compressed air blower for the fuel cell device, and power output/ power efficiency of the fuel cell device, and output/efficiency of the electric generator the improved. |
