<P>PROBLEM TO BE SOLVED: To provide a fuel cell system that allows easy determination of whether or not the function of closing a shutoff valve is normal and the level of airtightness of a passage portion is normal. <P>SOLUTION: When a shutoff valve 69 is in an open state and a first gas conveyance source 60 is being driven so as to convey fuel gas downstream of the first gas conveyance source 60, a control section 100 closes the shutoff valve 69 while driving the first gas conveyance source 60. When pressure in a passage portion 6m is reduced to a specified pressure or lower after the shutoff valve 69 is closed, the control section 100 determines that the function of closing the shutoff valve 69 is normal and that the level of airtightness of the passage portion 6m is normal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
