The invention discloses a hydrogen fuel cell steam-water separator and a drainage control method. The steam-water separator comprises a shell, and a steam-water separation cavity is formed in the shell; an air outlet communicated with the steam-water separation cavity is formed in the top of the shell, an air inlet communicated with the steam-water separation cavity is formed in the upper end of the side wall of the shell, a main drainage pipe communicated with the steam-water separation cavity is arranged at the bottom of the shell, and a first electromagnetic valve is arranged on the main drainage pipe; a water flow buffer cavity is formed between the inner side wall of the shell and the side wall of the steam-water separation cavity, and the bottom of the water flow buffer cavity communicates with an auxiliary drainage pipe; a second electromagnetic valve and a third electromagnetic valve are oppositely arranged on the side wall of the steam-water separation cavity; the steam-water separator further comprises a control unit, and the control unit is connected with the first electromagnetic valve, the second electromagnetic valve, the third electromagnetic valve and the liquid level sensor. The control unit is further connected with a tilt angle sensor. According to the invention, the problem that the pile is damaged due to the fact that water possibly flows back to the air inlet or the air outlet when the engineering machinery continuously goes up the abrupt slope and goes down the abrupt slope for a long time is solved.

    本发明公开一种氢燃料电池汽水分离器及排水控制方法,汽水分离器包括壳体,壳体内设置有汽水分离腔;壳体顶部设置有与汽水分离腔连通的出气口,壳体的侧壁上端设置有与汽水分离腔连通的进气口,壳体的底部设置有与汽水分离腔连通的主排水管,主排水管上设置有第一电磁阀;壳体的内侧壁与汽水分离腔的侧壁之间形成有水流缓冲腔,水流缓冲腔的底部连通有副排水管;汽水分离腔的侧壁上相对设置有第二电磁阀和第三电磁阀;汽水分离器还包括控制单元,控制单元与第一电磁阀、第二电磁阀、第三电磁阀及液位传感器连接;控制单元还连接有倾角传感器。本发明解决了工程机械连续上陡坡和长时间下陡坡水可能回流至进气口或出气口造成电堆损伤的问题。
