Abstract
A controller of a fuel cell system performs cathode gas supply control to raise an average cell voltage of a fuel cell stack by increasing supply of cathode gas to the fuel cell stack, when electric power required to be generated by the fuel cell stack is equal to zero, and the average cell voltage is lower than a predetermined target voltage. Under the cathode gas supply control, the controller sets the target voltage when a predetermined condition indicating that crossleak is likely to occur is satisfied, to a value higher than a reference target voltage as the target voltage in the case where the condition is not satisfied.
