摘要： A water electrolysis system includes a high-pressure hydrogen production unit for electrolyzing water to generate oxygen and high-pressure hydrogen (the pressure of the high-pressure hydrogen being higher than that of the oxygen), and a gas-liquid separation unit for removing water contained in the high-pressure hydrogen. The gas-liquid separation unit is placed on a hydrogen pipe for discharging the high-pressure hydrogen from the high-pressure hydrogen production unit. In addition, the water electrolysis system includes a high-pressure hydrogen supply pipe for transferring dewatered high-pressure hydrogen from the gas-liquid separation unit, a cooling unit, which is placed on the high-pressure hydrogen supply pipe and is capable of variably controlling the temperature of the high-pressure hydrogen to adjust the humidity of the high-pressure hydrogen, and a control unit.

摘要： In a method of stopping an operation of a water electrolysis system, an on-off valve disposed in a pressure release line communicating with a cathode side of an electrolytic membrane is opened while an electrolytic current is applied between power feeders to electrolyze water for generating oxygen on an anode side of the electrolytic membrane and high pressure hydrogen having a higher pressure than a pressure of the oxygen on the cathode side. A value of the electrolytic current is reduced in a predetermined cycle or continuously. One of a specific resistance and conductivity of water to be supplied to the high pressure hydrogen producing apparatus is detected. The value of the electrolytic current is increased if the specific resistance is equal to or lower than a first predetermined value, or if the conductivity is equal to or higher than a second predetermined value.
