PURPOSE:To simplify equipment by disposing a mist generating part in part of inlet gas piping which is the reaction gas supply passage to a fuel cell to provide the reaction gas supply passage and the cooling medium mist supply passage to the fuel cell in common. CONSTITUTION:A mist generating part 5 is disposed in part of inlet gas piping 3 as a reaction gas supply passage, and a heat exchanger 6 is disposed in part of outlet gas piping 4. Cooling medium which is liquefied by the heat exchanger 6 is returned to the mist generating part 5 by a pump 7, and formed into mist by actuating gas supplied from actuating gas piping 8, and it is supplied again to a fuel cell 1. Thus the reaction gas supply passage and the cooling medium mist supply passage to the fuel cell are provided in common, so a passage for cooling medium need not be provided in the reaction gas supply passage, and cooling structure is simplified. |
