<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which performs fault diagnosis of a valve provided in a raw fuel passage during leakage diagnosis of raw fuel in a stop state where a fuel cell system is not operating. <P>SOLUTION: A fuel cell system 1 comprises a fuel cell 2, a hydrogen generator 3, and a controller 19. In a stop state where the fuel cell 2 and the hydrogen generator 3 are stopping, the controller 19 performs a fixation check in order to detect whether or not a second valve 9 and a fourth valve 15 are opened for an open command, thus performing the fixation check of the valve and an open failure check of the valve during leakage diagnosis of raw fuel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
