The invention discloses a fuel cell cooling system, a cooling method and a cooling ejector. The cooling system comprises a fuel cell main body, the radiator is connected with the fuel cell; the fan and the cooling ejector are arranged on the two sides of the radiator respectively, a water mist nozzle is arranged at a second fluid inlet of the cooling ejector, a fan is connected to a first fluid inlet of the cooling ejector, and external air is introduced into the fan through a first three-way valve. Latent heat of vaporization can be utilized in the two modes of fuel cell exhaust and recovered liquid water ultrasonic atomization, and liquid water generated by the fuel cell can be used as a radiator to dissipate heat to the maximum extent. Especially in hot summer, although the recovered liquid water is little, the heat can still be dissipated by utilizing the latent heat of vaporization of the liquid water in the exhaust gas of the fuel cell.

    本发明公开了一种燃料电池冷却系统、冷却方法及冷却引射器,冷却系统包括燃料电池主体;与所述燃料电池相连的散热器;风扇以及冷却引射器分别设置于所述散热器的两侧,所述冷却引射器的第二流体入口处设置有水雾喷嘴,所述冷却引射器的第一流体入口处连接有风机,所述风机通过三通阀一引入外界的空气。本发明燃料电池排气和回收的液态水超声波雾化两种方式均可利用汽化潜热,燃料电池生成的液态水可以极大限度地被用作散热器散热。尤其在炎热的夏季,回收的液态水虽然很少,但仍然可以利用燃料电池排气中的液态水的汽化潜热散热。
