The invention provides a fuel cell control method and device, a vehicle and a storage medium, and the method comprises the steps: calculating the current vehicle request power under the condition of determining that the current energy mode of the vehicle is a pure hydrogen mode; when the vehicle request power is smaller than the target power of the fuel cell, whether the current charge state value of the power cell is larger than a first preset threshold value or not is determined, and the target power is the output power corresponding to the highest efficiency point of the fuel cell; when the current charge state value is smaller than or equal to a first preset threshold value, the fuel cell is requested to output the target power, and a power battery is charged through the difference value power between the target power and the whole vehicle request power; in the charging process of the power battery, if it is detected that the current state-of-charge value of the power battery is larger than the first preset threshold value, the fuel battery is controlled to enter the hot standby state. The method can prevent the fuel cell from frequently entering the hot standby.

    本申请提供了一种燃料电池的控制方法、装置、车辆和存储介质,该方法包括:在确定车辆的当前能源模式为纯氢模式的情况下,计算当前的整车请求功率;当整车请求功率小于燃料电池的目标功率时,确定动力电池的当前荷电状态值是否大于第一预设阈值,目标功率为燃料电池的最高效率点对应的输出功率;当所述当前荷电状态值小于或等于第一预设阈值时,请求所述燃料电池输出所述目标功率,并利用目标功率与整车请求功率之间的差值功率,对动力电池充电;在对动力电池充电的过程中,若检测到动力电池的当前荷电状态值大于所述第一预设阈值,则控制燃料电池进入热待机状态。该方法能够避免燃料电池频繁进入热待机。
