Abstract
A hydrogen generating system is equipped with a water electrolysis unit for producing hydrogen by performing electrolysis on pure water supplied from a pure water supply apparatus, with a back-pressure valve mechanism disposed in a hydrogen outlet port of the water electrolysis unit. The back-pressure valve mechanism is equipped with a first back-pressure valve, which sets a first back pressure, for discharging hydrogen to the outside of a hydrogen supply passage, and a second back-pressure valve, which sets a second back pressure at a higher pressure than the first back pressure, for extracting high-pressure hydrogen into the hydrogen supply passage.
