A fuel cell system includes: an oxidizing gas supply shut valve; an oxidizing gas exhaust shut valve; a cathode pressure measuring unit as a pressure detection unit for detecting a cathode pressure value which is a pressure of a channel between the oxidizing gas supply shut valve and the oxidizing gas exhaust shut valve; a stop processing unit which closes the oxidizing gas supply shut valve and the oxidizing gas exhaust shut valve when operation of the fuel cell stack is stopped; and a judgment unit which judges whether the operations of the oxidizing gas supply shut valve and the oxidizing gas exhaust shut valve have failed according to the cathode pressure value upon stop when the operation of the fuel cell stack is stopped and the cathode pressure value upon start when the operation of the fuel cell stack is started after the stop. |
