Hydrogen supply subsystem module and fuel cell

The utility model relates to the technical field of fuel cells, in particular to a hydrogen supply subsystem module and a fuel cell, the hydrogen supply subsystem module comprises a stop valve, a proportional valve and an ejector, the stop valve, the proportional valve and the ejector are all fixed on a base, the stop valve is communicated with the proportional valve, the base is provided with a hydrogen inlet hole and a hydrogen outlet hole, and the hydrogen inlet hole is communicated with the proportional valve. The hydrogen inlet hole is communicated with an inlet of the stop valve, an outlet of the ejector is communicated with an inlet of the electric pile through the hydrogen outlet hole, and a first flow channel is further formed in the base and used for communicating the proportional valve and the ejector. The base is arranged, the stop valve, the proportional valve and the ejector are integrated into a whole, the hydrogen inlet hole, the hydrogen outlet hole and the first flow channel are formed in th
