PROBLEM TO BE SOLVED: To provide a fuel cell system capable of most effectively utilizing the capacity of a capacitor when generated power is changed over.SOLUTION: When an open-circuit voltage Vof a capacitor 6 drops below a prescribed first threshold Vwhile a fuel cell stack 1 is generating power with a prescribed intermediate power P, an ECU 8 of a fuel cell system 100 exerts control to change a generated power Pof the fuel cell stack 1 from the intermediate power Pto a maximum power P. The prescribed first threshold Vis determined on the basis of the maximum power P, the intermediate power P, a capacity C of the capacitor 6, a minimum permissible voltage Vof the capacitor 6, and a power rise rate α at which the generated power Prises from the intermediate power Pto the maximum power P. |
