Abstract

An operation method for a water electrolyzer, including an electrolyzer for electrolyzing water, a hydrogen separator to which hydrogen generated in the electrolyzer is to be led, an oxygen separator to which oxygen generated in the electrolyzer is to be led, and a vent line for discharging gas from the hydrogen separator or the oxygen separator and a vent valve disposed in the vent line, includes: a step of stopping electrolysis of water in the electrolyzer; a step of determining whether a first indicator indicating an increase amount of an oxygen concentration in gas in the hydrogen separator or of a hydrogen concentration in gas in the oxygen separator after stopping the electrolysis exceeds a first threshold; and opening, when the first indicator exceeds the first threshold, the vent valve to decrease a pressure of the hydrogen separator or the oxygen separator to a first specified value.
