The invention provides a fuel cell vehicle and a control method thereof. The fuel cell vehicle includes a fuel cell, a gas supply unit, a friction brake system, a drive motor, an electric storage device, and a control unit configured to execute control of obtaining requested braking force with use of friction braking force and regenerative braking force and control of performing a scavenging process. When the fuel cell vehicle is in braking with the friction braking force and the regenerative braking force, the control unit is configured to determine whether or not a scavenging preparation condition is satisfied with use of the amount of stagnant water stagnating in the fuel cell, execute a responsiveness enhancement process when the scavenging preparation condition is executed, and execute a scavenging process when the responsiveness enhancement process is completed, and the amount of the stagnant water reaches a reference value.
本发明提供燃料电池车辆以及燃料电池车辆的控制方法。燃料电池车辆具备燃料电池、气体供给部、摩擦制动系统、驱动马达、蓄电装置以及控制部,该控制部执行使用摩擦制动力和再生制动力来获得被请求的制动力的控制、和用于进行扫气处理的控制。在燃料电池车辆通过摩擦制动力和再生制动力处于制动中时,控制部使用滞留在燃料电池的内部的滞留水的量来判断是否满足扫气准备条件,在满足扫气准备条件时执行响应性提高处理,在响应性提高处理完成且滞留水的量达到基准值时执行扫气处理。
