PROBLEM TO BE SOLVED: To provide a power control device for a vehicular fuel cell, capable of suppressing an oxidation reduction reaction on catalyst layers of a fuel electrode and an air electrode in increasing output power of a fuel cell in response to an increase in required output in an accelerator depression operation so that deterioration due to the aggregation/elution of platinum in the catalyst layers can be reliably prevented.SOLUTION: In the case where an accelerator depression operation is performed while an SOC of a secondary battery 3 is less than an SOC determination value S (S1 is Yes), the output power of a fuel cell 4a is increased as usual when an accelerator opening APS is equal to or more than a first accelerator determination value A1 (S2-3), while an increase in output power is suppressed more than usual when the accelerator opening APS is less than the first accelerator determination value A1 (S2-4).SELECTED DRAWING: Figure 3
【課題】アクセル踏込み操作時の要求出力の増加に呼応して燃料電池の出力電力を増加させる際に、燃料極や空気極の触媒層上の酸化還元反応を抑制でき、これにより触媒層の白金凝集・溶出に起因する劣化を確実に防止できる車両用燃料電池の電力制御装置を提供する。【解決手段】2次電池3のSOCがSOC判定値S未満の状態でアクセル踏込み操作が行われた場合(S1がYes)、アクセル開度APSが第1のアクセル判定値A1以上のときには、燃料電池4aの出力電力を通常通り増加させる一方(S2−3)、アクセル開度APSが第1のアクセル判定値A1未満のときには、出力電力の増加を通常時よりも抑制する(S2−4)。【選択図】図3
