The invention discloses a drainage control method, device and system of a fuel cell, a vehicle and a medium, and relates to the technical field of fuel cells, and the method can obtain the gaseous water flow at an anode inlet of the fuel cell, the water flow entering an anode from a cathode and the saturated water vapor flow at an anode outlet of the fuel cell in real time. The total water flow generated by the fuel cell in the current power generation state and the saturated steam flow of the anode outlet of the fuel cell are combined to calculate the water flow of liquid water at the anode outlet of the fuel cell, and the opening time of the drain valve is adjusted by referring to the water flow of the liquid water. Therefore, the adjusted starting time can be matched with the current power generation state of the fuel cell, liquid water generated in the power generation state is discharged to the outside, and the accuracy of drainage control is improved.

    本发明公开了一种燃料电池的排水控制方法、装置、系统、车辆及介质,涉及燃料电池技术领域,该方法可实时获取燃料电池阳极入口的气态水流量、由阴极进入阳极的水流量,以及燃料电池阳极出口处的饱和水蒸气流量,以结合燃料电池在当前发电状态下产生的总的水流量和燃料电池阳极出口的饱和水蒸气流量,计算得到在燃料电池阳极出口处将变为液态水的水流量,参考该液态水的水流量调整排水阀的开启时刻,以使得调整后的开启时刻能够匹配燃料电池当前的发电状态,将该发电状态下产生的液态水排到外界,提升排水控制的精准度。
