Abstract
A water electrolysis system is equipped with a water electrolysis device, a water supply passage, a hydrogen supply passage, a gas-liquid separator, a first water drainage passage, a first water drainage valve, a second water drainage valve, a determination unit, and a valve control unit. In a method of stopping operation of the water electrolysis system, in a water drainage step, in the case that the determination unit determines that operation of the water electrolysis device has been stopped, the first water drainage valve is controlled to be placed in a valve open state, thereby draining liquid water from the gas-liquid separator into the first water drainage passage.
