<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of controlling an electrolyte film in a proper wet state when restarting a fuel cell. <P>SOLUTION: A voltage in each cell of the fuel cell 1 is detected by a voltage sensor 15, the inside of the fuel cell 1 is determined to be in a more humidified state than usual when only the voltages of a part of cells drop, and the inside of the fuel cell 1 is in more dry state than usual when the voltages of all cells similarly drop. When the fuel cell 1 stops, before stopping supply of a fuel gas, the fuel gas pressure of an anode pole 3 is adjusted to a value corresponding to a wet state in the fuel cell 1. When the fuel cell 1 stops, water is generated correspondingly to the fuel gas pressure in the anode pole 3 to adjust the wet state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
