To provide an art capable of reducing possibility that a power storage amount of a secondary battery reaches to a prescribed lower limit value.SOLUTION: A vehicle includes: a power consumption source; a fuel battery; a secondary battery, and a control part. The control part decides a power generation amount of the fuel battery using a requested power amount of the power consumption source and a power storage amount of the secondary battery when load limitation on the fuel battery is not performed, and decides the smaller one of (i) the generated power amount capable of being generated by the fuel battery during an output limitation time and (ii) the sum of the request charged power of the secondary battery calculated from the charged power of the secondary battery and the requested power amount of the power consumption source, as the power generation amount of the fuel battery when the load limitation on the fuel battery is performed.SELECTED DRAWING: Figure 6 【課題】二次電池の蓄電量が予め定められた下限値に至る可能性を低減できる技術を提供する。【解決手段】車両は、電力消費源と燃料電池と二次電池と制御部とを備え、制御部は、燃料電池の出力制限が行われていない場合には、電力消費源の要求電力量と、二次電池の蓄電量とを用いて燃料電池の発電量を決定し、燃料電池の出力制限が行われている場合には、（ｉ）出力制限時における燃料電池が発電可能な発電量と、（ｉｉ）二次電池の蓄電量から算出された前記二次電池の要求充電量と電力消費源の要求電力量との和と、のうち小さい方を燃料電池の発電量として決定する。【選択図】図６
