摘要： In a fuel cell system, regeneration-time voltage fixed control is implemented where during regeneration or when regeneration is expected to occur, output voltage of a fuel cell is set to a voltage value outside an oxidation reduction progress voltage range, and the amount of reactant gas supplied to the fuel cell is changed based on the amount of electric power remaining in an energy storage device. In the regeneration-time voltage fixed control, it is determined whether or not regeneration occurs while a moving body equipped with the fuel cell system is moving down a slope, and in the case where it is determined that regeneration occurs while the moving body is moving down a slope, the amount of the reactant gas supplied to the fuel cell is decreased in comparison with the case where it is determined that regeneration occurs while the moving body is not moving down a slope.

摘要： A fuel cell vehicle is provided. The voltage of a fuel cell is fixed, by a DC/DC converter, to a voltage outside an oxidation reduction progress voltage range of the fuel cell. In this state, oxygen concentration or hydrogen concentration is decreased by a gas supply unit, and electric power outputted from the fuel cell is decreased. In this state, regenerative electric power generated by regeneration is collected into a battery.
