PROBLEM TO BE SOLVED: To reduce degradation of acceleration feeling with respect to an accelerator stepping-down amount at acceleration 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 motor 136 driving the vehicle; a pump (FC accessories 150) that supplies oxygen to the fuel cell; an accelerator position detection unit 190 that detects an accelerator stepping-down amount of the vehicle; 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 and that controls the pump on the basis of the drive request power. The control unit calculates the drive request power so that a rate of an increase in the drive request power is higher than a rate of an increase in the power generation request power when the calculated power generation request power increases.SELECTED DRAWING: Figure 1
【課題】燃料電池車両の加速時におけるアクセル踏込量に対する加速感の悪化を低減する。【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、車両を駆動するモーター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、車両の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とともに、駆動要求電力に基づいてポンプを制御する制御部180とを備える。制御部は、算出する発電要求電力が増加するときに、発電要求電力の増加速度よりも駆動要求電力の増加速度が速くなるように駆動要求電力を算出する。【選択図】図1
