Abstract
A fuel cell system includes an anode gas flow passage in which an injector is disposed, a plurality of pressure sensors that measures a pressure value in the anode gas flow passage closer to the fuel cell stack than to the injector, and a control unit configured to control an output of the fuel cell stack by adjusting an amount of supplied anode gas using the measured pressure values. The control unit limits the output of the fuel cell stack when a first condition that a state in which a deviation, of a plurality of pressure values measured by the plurality of pressure sensors is equal to or greater than a predetermined first threshold value is maintained for a predetermined time or more has been satisfied compared with when the first condition has not been satisfied.
