<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which it is prevented that cooling water cooled by a radiator wherein there is temperature difference from fuel cell temperature flows into a fuel cell after power generation of the fuel cell is stopped. <P>SOLUTION: A power generation and stop mode switching determination part 31 of a controller 30 carries out switching determination of two operation modes of a normal power generation mode to carry out normal power generation or a power generation stop mode to stop power generation based on accelerator opening, a car speed, and battery information. In power generation and stop mode, a compressor is stopped by a compressor control part 33, a hydrogen pressure valve is stopped by a hydrogen pressure-adjusting valve control part 35, and a power manager control part 34 stops taking out of an electric power from the fuel cell. If the temperature difference between cooling water temperature of the fuel cell exit and that of the radiator exit is small, a cooling system control part 32 suppresses the operation of a cooling water pump. <P>COPYRIGHT: (C)2009,JPO&INPIT |
