The invention relates to a water management method of a fuel cell stack. According to the method, a gyroscope is mounted in a vehicle carrying a fuel cell engine system; the gyroscope is connected with a fuel cell stack of the fuel cell engine system, senses the stable running state of the vehicle, and controls the current density of the fuel cell stack to be increased to 1500 mAcm<-2> or above ifthe vehicle is detected to turn or climb a slope or descend the slope. Compared with the prior art, the method has the advantages of simplicity in operation, low control cost, quickness in control, convenience in drainage of the fuel cell and the like.
本发明涉及一种燃料电池电堆的水管理方法,该方法在搭载燃料电池发动机系统的车辆内安装陀螺仪,所述的陀螺仪连接燃料电池发动机系统的燃料电池电堆,所述的陀螺仪感知车辆运行的平稳状况,若检测到车辆发生转弯、爬坡或下坡,则陀螺仪控制燃料电池电堆的电流密度提高至1500mAcm以上。与现有技术相比,本发明具有操作简单,控制成本低,控制快速且方便燃料电池排水等优点。
