The invention relates to a ventilation control method and device for a fuel cell, a vehicle and a storage medium, and the method comprises the steps: carrying out the integration of the working current and voltage of a galvanic pile, obtaining the hydrogen accumulation amount in a current galvanic pile shell through an integration method, and obtaining the cooling outlet water temperature of the galvanic pile if the hydrogen accumulation amount in the current galvanic pile shell is greater than a preset threshold value, when the cooling outlet water temperature is smaller than a first preset temperature value, the rotating speed of the air compressor is increased according to a preset speed increasing strategy, so that pressurized gas is introduced into the galvanic pile through the first pipeline and the second pipeline, and the purging outlet temperature of the galvanic pile is obtained; and if the purging outlet temperature of the electric pile is smaller than a second preset temperature value, purging the electric pile according to a first purging amount, detecting whether the current purging duration is greater than the first accumulated purging duration, and if the current purging duration is greater than the first accumulated purging duration, stopping purging. Therefore, an additional hydrogen concentration sensor is not needed, hydrogen accumulated in the shell can be effectively removed, and the cost and the power consumption of the whole machine are reduced.
本申请涉及一种燃料电池的通风控制方法、装置、车辆及存储介质,方法包括:对电堆工作电流、电压进行积分,利用积分法获取当前电堆壳体内的氢气积聚量,若当前电堆壳体内的氢气积聚量大于预设阈值,则获取电堆的冷却出口水温,并在冷却出口水温小于第一预设温度值时,按照预设增速策略增大空压机的转速,以通过第一管路和第二管路向电堆通入加压气体,并获取电堆的吹扫出口温度;若电堆的吹扫出口温度小于第二预设温度值,则按照第一吹扫量对电堆进行吹扫,并检测当前吹扫时长是否大于第一累计吹扫时长,若当前吹扫时长大于第一累计吹扫时长,则停止吹扫。由此,不用额外的氢浓度传感器,能够有效去除积聚在壳体内部的氢气,降低整机成本和功耗。
