Abstract:
A controller closes a cutoff valve and a purge valve when a pressure value detected by a pressure sensor is an abnormal value. The controller then judges that an on-off valve has failed when the pressure value detected by the pressure sensor P 1  has lowered, whereas the controller judges that the pressure sensor has failed when the pressure value detected by the pressure sensor has not lowered.

Claim (Index 7):
The fuel cell system according to  claim 2 , further comprising:\n a pressure regulating valve between the on-off valve and the cutoff valve, the pressure regulating valve reducing a pressure of the fuel gas; a third pressure sensor which detects a pressure of the fuel gas inside a passage between the on-off valve and the pressure regulating valve; and a fourth pressure sensor which detects a pressure of the fuel gas inside a passage between the pressure regulating valve and the cutoff valve, wherein: the controller causes, after closing the cutoff valve, the third pressure sensor and the fourth pressure sensor to monitor pressure reduction, and as a result of the monitoring, if pressure reduction is observed by the third pressure sensor and the fourth pressure sensor, the controller judges whether or not the pressure value detected by the first pressure sensor has lowered, whereas, if pressure reduction is not observed by at least one of the third and forth pressure sensors, the controller judges that the first pressure sensor has failed.
