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 11):
The fuel cell system according to  claim 9 , 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 stops the power generation of the fuel cell after pressure values detected by the third pressure sensor and the fourth pressure sensor become equal to each other, after limiting the output of the fuel cell; and the controller then maintains a stopped state of the power generation of the fuel cell when judging that the on-off valve has failed, whereas the controller restarts the power generation of the fuel cell by opening the cutoff valve when judging that the first pressure sensor has failed.
