In a fuel cell system including a load and a fuel cell stack connected to the load and supplying an anode gas and a cathode gas to the fuel cell stack to generate power according to the load, the fuel cell system includes, a pressure setting unit configured to set a pressure of the anode gas higher when the load is high as compared with when the load is low, a stagnation point determination unit configured to determine, according to a state of power generation of the fuel cell stack, whether or not a nitrogen stagnation point is left in a reaction flow path within the fuel cell stack, and an operation control unit configured to performs an operation while preventing the pressure of the anode gas from being lowered when a required load is lowered in a state where the nitrogen stagnation point is left. |
