The invention discloses a hydrogen fuel cell hydrogen ejection recovery system, which comprises an ejector, the ejector is connected with a hydrogen inlet and a circulating hydrogen outlet of a galvanic pile, the hydrogen outlet and the circulating hydrogen inlet of the galvanic pile are connected with a moisture hydrogen discharge valve, and the circulating hydrogen outlet and the circulating hydrogen inlet are communicated through a galvanic pile internal pipeline. According to the system, the hydrogen outlet and the circulating hydrogen inlet of the galvanic pile adopt the veneering type moisture hydrogen discharging valves, and the baffles are arranged in the moisture hydrogen discharging valves, so that liquid water in hydrogen can be efficiently separated and discharged. The water hydrogen discharging valve is not connected with the electric pile through a pipeline, so that the hydrogen leakage risk is greatly reduced, the internal flow resistance is reduced, and the use of a hydrogen circulating pump i
