Embodiment Construction
[0007] Embodiments are described below in conjunction with the accompanying drawings.
[0008] Two fuel cell stacks (1# and 2#) form a battery pair 5, and the hydrogen system consists of a hydrogen pressure regulating valve 1, a humidifier 2, a three-way valve 3, an air intake pipe 4, a connecting pipe 6 and a gas-water separator 7 . During the working process, the hydrogen flows into the 1# battery stack of the battery pair 5 through the pressure regulating valve 1, the humidifier 2, the three-way valve 3, and a branch of the intake pipe 4, and then passes through the connecting pipe 6 and the gas-water flow on the connecting pipe. The separator 7 flows into the 2# battery stack of the battery pair; after a certain time interval, the three-way valve 3 switches the channel, the branch pipe channel just ventilated on the intake pipe 4 is cut off, and the other branch pipe is opened, and the air flow first enters the 2# battery stack , and then flow into the 1# battery stack th...
