The invention relates to a control method and device of a fuel cell, electronic equipment and a vehicle. The method comprises the following steps: acquiring a stack-out temperature of the fuel cell of the vehicle; when the out-of-stack temperature is smaller than a preset starting temperature threshold value, the single cell voltage of the fuel cell is determined based on the out-of-stack temperature, so that the fuel cell is controlled to enter a reduction state through the single cell voltage, and reversible attenuation of the fuel cell is recovered; when the out-of-stack temperature is larger than or equal to a preset starting temperature threshold value, the power battery SOC of the vehicle is obtained, and when the power battery SOC is larger than a preset SOC threshold value, the single battery voltage of the fuel battery is determined, so that the fuel battery is controlled to enter a reduction state through the single battery voltage, and reversible attenuation of the fuel battery is recovered. The fuel cell attenuation rate can be reduced, the service life of the fuel cell is prolonged, the power generation efficiency of the fuel cell is improved, vehicle hydrogen consumption is reduced, and economical efficiency and vehicle safety are improved.

    本公开涉及一种燃料电池的控制方法、装置、电子设备及车辆,该方法包括:获取车辆燃料电池的出堆温度;当出堆温度小于预设启动温度阈值时,基于出堆温度,确定燃料电池的单片电池电压,以通过单片电池电压控制燃料电池进入还原状态,恢复燃料电池的可逆衰减;当出堆温度大于或等于预设启动温度阈值时,获取车辆的动力电池SOC,并在动力电池SOC大于预设SOC阈值时,确定燃料电池的单片电池电压,以通过单片电池电压控制燃料电池进入还原状态,恢复燃料电池的可逆衰减。能够降低燃料电池衰减速率,提高燃料电池的使用寿命和发电效率,从而降低车辆氢耗,提高经济性和车辆的安全性。
