The invention discloses a fuel cell control method of a hydrogen fuel cell vehicle, and belongs to the field of pure electric vehicles. The fuel cell control method of a hydrogen fuel cell vehicle comprises the following steps: 1) in a hybrid mode, acquiring a vehicle state; 2) judging whether the change frequency of a vehicle demand power is smaller than a preset value or not according to the obtained vehicle state; 3) determining a control mode of the fuel cell according to a judgment result; if the vehicle demand power change frequency is smaller than the preset value, enabling the fuel cell to enter a two-parameter control mode; otherwise, enabling the fuel cell to enter a single-parameter power cell SOC control mode. According to the control method, on the premise that vehicle power is met, it can be guaranteed that output of the fuel cell is stable as much as possible, and therefore the service life of the fuel cell is prolonged.

    本发明公开了一种氢燃料电池车辆的燃料电池控制方法,属于纯电动车领域。一种氢燃料电池车辆的燃料电池控制方法,包括以下步骤:1)在混动模式下,获取车辆状态;2)根据获取的车辆状态,判断车辆需求功率的变化频率是否小于预设值;3)根据判断结果决定燃料电池的控制模式;若车辆需求功率变化频率的小于预设值,则燃料电池进入双参数控制模式;否则,则燃料电池进入单参数动力电池SOC控制模式。本发明的控制方法,在满足车辆动力的前提下能够保证燃料电池的输出尽可能的平稳,从而提高燃料电池的寿命。
