摘要： A fuel cell system includes an idle stop unit, a discharger, a power-generation-state memory, and an initial-current-value setter. The idle stop unit is configured to stop a supply of the reactant gas to a fuel cell. The discharger is configured to allow the fuel cell to generate the electric power with the reactant gas remaining in the fuel cell after the idle stop unit stops the supply of the reactant gas and is configured to discharge electric current to a current receiver. The power-generation-state memory is configured to store a power-generation state of the fuel cell immediately before the idle stop unit stops the supply of the reactant gas. The initial-current-value setter is configured to set an initial current value of the fuel cell discharged by the discharger on a basis of the power-generation state of the fuel cell stored in the power-generation-state memory.
