PROBLEM TO BE SOLVED: To suppress occurrence of torque shock during deceleration of a fuel cell vehicle.SOLUTION: A fuel cell system 100 mounted on a fuel cell vehicle 10 comprises: a fuel cell 110 that supplies electric power to a driving motor 136 of the vehicle; a pump (FC auxiliary equipment 150) that supplies oxygen to the fuel cell; an accelerator position detection unit 190 that detects an accelerator stepping-down amount; and a control unit 180 that calculates power generation request power of the fuel cell and drive request power of the pump on the basis of the accelerator stepping-down amount. The control unit calculates the drive request power so that a rate of decrease of the drive request power is higher than a rate of decrease of the power generation request power and sets a lower limit value to the calculated drive request power when a condition set in advance as a condition that the power generation request power rapidly decreases is satisfied, and controls the pump to execute the drive corresponding to the lower limit.SELECTED DRAWING: Figure 1
【課題】燃料電池車両の減速時におけるトルクショックの発生を抑制する。【解決手段】燃料電池車両10に搭載される燃料電池システム100は、車両の駆動モーター136に電力を供給する燃料電池110と、酸素を燃料電池に供給するポンプ(FC補機150)と、アクセル踏込量を検出するアクセル位置検出部190と、アクセル踏込量に基づいて燃料電池の発電要求電力及びポンプの駆動要求電力を算出する制御部180とを備える。制御部は、発電要求電力が急減する条件として予め設定されている条件を満たした場合に、発電要求電力の減少速度よりも減少速度が速くなるように駆動要求電力を算出し、算出した駆動要求電力に対して下限値を設定して、駆動要求電力が下限値を下回る場合、ポンプに対して下限値に対応した駆動を実行させる。【選択図】図1
