[0054] System components include: hydrogen cylinder 1, stop valve 2, pressure reducing valve 3, second hydrogen injection valve 4, first hydrogen injection valve 5, ejector 6, gas-water separation assembly 7, fuel cell stack 8, drain valve 9 . The battery stack inlet 92 and the battery stack outlet 91 . High-pressure fresh hydrogen F1, the gas-liquid mixture F2 discharged from the stack, and the gas F3 from which the liquid droplets are separated. The structure of the ejector separator includes a nozzle 71 , a main body 72 , a swirl vane 73 , a gas-liquid mixture inlet 74 , an exhaust pipe 75 and a drain pipe 76 .
[0055] image 3 , is the system proposed in this scheme. The high-pressure hydrogen cylinder 1 stores high-pressure hydrogen as the fuel of the fuel cell stack 8, and after passing through the cut-off safety valve 2 and the pressure reducing valve 3, it is supplied to the ejector 6 (or Injector separator) has fresh hydrogen F1 with a certain pressure value.
