PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing an encapsulated anode gas from unnecessarily diffusing to the cathode electrode side at the time of system stop.SOLUTION: An fuel cell system comprises: an impedance detection unit for detecting internal impedance of a fuel cell after system stop request; a pressure control unit for controlling anode gas pressure of the fuel cell to predetermined pressure corresponding to the internal impedance; and a leaving/stopping processing unit for executing leaving/stopping processing while taking the predetermined pressure as leaving/stopping start pressure.SELECTED DRAWING: Figure 6 |
