Fuel cell vehicle

The present specification relates to a fuel cell vehicle in which a fuel cell and a battery cell are connected in parallel, and provides a technique capable of suppressing deterioration of the fuel cell more than in the prior art. A fuel cell vehicle disclosed in this specification is provided with a fuel cell unit, a battery unit, a motor for travel, and a controller. The battery unit is connected in parallel with the fuel cell unit. The motor operates by receiving power supply from at least one of the fuel cell unit and the battery unit. While driving of the motor is prohibited, the controller controls the fuel cell unit such that the output voltage of the fuel cell unit is maintained at a predetermined idle voltage that is greater than zero and lower than the output voltage of the battery unit. 本说明书涉及将燃料电池单元与蓄电池单元并联连接的燃料电池车，提供一种能够比以往更抑制燃料电池单元的劣化的技术。本说明书公开的燃料电池车具备燃料电池单元、蓄电池单元、行驶用的马达以及控制器。蓄电池单元与燃料电池单元并联连接。马达从燃料电池单元与蓄电池单元的至少一方接受电力供给来进行动作。在马达的驱动被禁止的期间，控制器以燃料电池单元的输出电压保持大于零且低于蓄电池单元的输出电压的规定的怠速电压的方式控制燃料电池单元。
