PROBLEM TO BE SOLVED: To provide a voltage control device for a fuel-cell vehicle capable of securing good acceleration responsiveness while suppressing battery deterioration even when a vehicle acceleration request is made in the situation where the output from the battery is restricted.SOLUTION: Provided is a voltage control device 100 of a fuel-cell vehicle. When the control unit determines that electric power suppliable from a secondary battery 50 to an air compressor MG1 is less than a lower limit of an acceleration maintaining-electric power of the air compressor MG1, the control unit maintains a state where the electric power generated by the fuel cell is consumed by electric power driven devices, and supplies the electric power which has been consumed by the electric power driven devices to the air compressor MG1 when a vehicle acceleration request is made.SELECTED DRAWING: Figure 3

    【課題】バッテリからの出力が制限されている状況で車両の加速要求が行われた場合であっても、良好な加速応答性を確保しながらバッテリの劣化を抑制することができる燃料電池車の電圧制御装置を提供する。【解決手段】燃料電池車の電圧制御装置100は、二次電池50からエアコンプレッサMG1に供給可能な電力が、エアコンプレッサMG1の加速維持電力の下限値を下回ると判定した場合に、燃料電池で発電した電力を電力駆動装置で消費している状態に維持し、車両加速要求が行われたときに電力駆動装置で消費させておいた電力をエアコンプレッサMG1に供給する。【選択図】図3
