The invention discloses a fuel cell control method and device, a vehicle and a storage medium. The method comprises the steps that after it is determined that a current vehicle enters a target state, the output power of a fuel cell system in the current vehicle is reduced to preset power; maintaining the voltage of an electric pile in the fuel cell system within a preset reduction voltage range by adjusting a target valve of an air path in the fuel cell system; by adjusting a proportional valve of a hydrogen path in the fuel cell system, the flow of hydrogen in the fuel cell system is kept within a preset flow range, and loading of an electric pile in the fuel cell system by a high-voltage loop is prohibited. According to the technical scheme provided by the embodiment of the invention, the fuel cell engine does not need to be stopped, the voltage of the electric pile is enabled to be at the reduction potential by adjusting the valve, and the hydrogen is enabled to circulate in the preset flow range, so that the attenuation of the electric pile performance is delayed, and the zero-power output of the electric pile is realized by prohibiting the loading of the electric pile by a high-voltage loop; and the hydrogen consumption is efficiently reduced.

    本发明公开了一种燃料电池的控制方法、装置、车辆及存储介质。该方法包括:在确定当前车辆进入目标状态后,将当前车辆中燃料电池系统的输出功率降低至预设功率;通过调节燃料电池系统中空气路的目标阀门,将燃料电池系统中的电堆电压保持在预设还原电压范围内;通过调节燃料电池系统中氢气路的比例阀,将燃料电池系统中氢气的流量保持在预设流量范围内,并禁止高压回路对燃料电池系统中电堆的拉载。本发明实施例的技术方案,无需将燃料电池发动机停机,通过调节阀门使电堆电压处于还原电位以及使氢气在预设流量内范围内进行循环,延缓了电堆性能的衰减,并通过禁止高压回路对进行电堆的拉载,实现电堆的零功率输出,高效降低了氢耗。
