The invention relates to a fuel cell stack and system, a fuel cell vehicle and a water management method thereof. A first end plate of the fuel cell stack is provided with a hydrogen inlet, an air inlet, a first hydrogen outlet and a first air outlet, a second end plate of the fuel cell stack is provided with a second hydrogen outlet and/or a second air outlet, the second hydrogen outlet and/or the second air outlet are/is provided with an electromagnetic valve, and the electromagnetic valve is connected with a control system of the fuel cell stack. The fuel cell stack and a gyroscope are arranged on the fuel cell vehicle. The gyroscope is used for monitoring the running condition of the vehicle in real time, if the gyroscope monitors that the stack turns or climbs or goes downhill, the electromagnetic valve is opened through the control system, the hydrogen and/or air outlet in the end plate on the other side is opened, water drainage is increased, and then the end of the stack is prevented from being flooded. Compared with the prior art, the method has the advantages of simplicity and feasibility in operation, low cost and the like.

    本发明涉及一种燃料电池电堆及系统、燃料电池汽车及其水管理方法,所述的燃料电池电堆在第一端板上设有氢气进口、空气进口、第一氢气出口、第一空气出口,第二端板上设有第二氢气出口和/或第二空气出口,第二氢气出口和/或第二空气出口设有电磁阀,电磁阀连接燃料电池电堆的控制系统;所述的燃料电池汽车上设有上述燃料电池电堆以及陀螺仪;本发明利用陀螺仪实时监控车辆运行的状况,若陀螺仪监测到电堆发生转弯、爬坡或下坡,则通过控制系统打开电磁阀,另一侧端板上的氢气和/或空气出口打开,增大排水,进而避免电堆端部水淹。与现有技术相比,本发明具有操作简单易行,成本低等优点。
