The invention discloses a zero-power output method for a fuel-electricity system of a fuel cell engine system. The bypass branch is arranged between the air inlet pipeline and the air tail exhaust pipeline, the bypass valve is arranged on the bypass branch, and therefore when the lithium battery is sufficient and does not need to be charged, the fuel-electricity system is subjected to load reduction to be in the idling working condition and is switched to be in the zero output state, the bypass valve is opened, and the fuel-electricity system can be charged. The generating capacity of the gas-electricity system is consumed by increasing the rotating speed of the air compressor, and the excessive air entering the gas-electricity system is discharged through the bypass branch when the rotating speed of the air compressor is increased, so that the gas-electricity system is not shut down, the start-stop frequency of the gas-electricity system is greatly reduced, and the performance attenuation of the gas-electricity system is slowed down.

    本发明公开了一种燃料电池发动机系统的燃电系统零功率输出方法。本发明通过在所述空气进气管路与空气尾排管路之间设有旁通支路,所述旁通支路上设有旁通阀,从而可以在锂电电量充足不需要充电时,燃电系统降载到怠速工况并切换为零输出状态,打开旁通阀,通过提高空压机的转速来把燃电系统的发电量消耗掉,而空压机转速提高所进入的多余空气通过旁通支路排出,从而实现燃电系统不关机,大大降低燃电系统的启停次数,减缓燃电系统性能的衰减。
