PROBLEM TO BE SOLVED: To provide a water electrolysis system that can be fabricated into a simple, economical structure, is capable of protecting low-temperature components from high temperatures and enables effective use of exhaust heat.SOLUTION: The water electrolysis system 10 includes: a water electrolyzer 12 that produces high-pressure hydrogen by electrolyzing pure water; a water circulator 14 that circulates the water to the water electrolyzer 12; a gas-liquid separator 16 that separates oxygen and high-pressure hydrogen discharged from the water electrolyzer 12 from the water inside the water circulation device 14; the water circulator 14 that circulates the water pooled in the gas-liquid separator 16 to the water electrolyzer 12; and an air feeder 90 that feeds air for dilution to the gas-liquid separator 16, which are all housed in a casing 22. The air feeder 90 includes a single air blower 92 that has both a heat recovery function for recovering heat generated in the water electrolyzer 12 and an air blowing function for supplying the heat along with the air for dilution to the gas-liquid separator 16. |
