摘要： A method for operating a water electrolysis system includes determining whether or not a water electrolysis apparatus is shut down. The water electrolysis system includes the water electrolysis apparatus, a water circulation apparatus, and a gas-liquid separation apparatus. The water electrolysis apparatus includes power feeders provided on an anode side and a cathode side of an electrolyte membrane. The water electrolysis apparatus generates oxygen on the anode side and generates hydrogen on the cathode side at a higher pressure than a pressure of the oxygen by electrolysis of water. Pressure on the cathode side is released when it is determined that the water electrolysis apparatus is shut down. The water circulation apparatus is operated until a concentration of hydrogen remaining on the anode side is a specified value or less under a condition in which a release of pressure on the cathode side is completed.

摘要： A water electrolysis apparatus applies an electrolysis voltage between current collectors disposed on the respective sides of an electrolyte membrane thereby to electrolyze water to generate oxygen in an anode electrolysis chamber and hydrogen in a cathode electrolysis chamber under a pressure higher than a normal pressure. The water electrolysis apparatus is shut down by applying a voltage between the current collectors after the cathode electrolysis chamber stops supplying the hydrogen, reducing a pressure in at least the cathode electrolysis chamber while the voltage is being applied, and stopping applying the voltage when the pressure in the cathode electrolysis chamber is equal to a pressure in the anode electrolysis chamber.

摘要： The invention provides a high-pressure hydrogen production apparatus for preventing hydrogen gas from leaking toward an anode side and for obtaining excellent electrolytic efficiency. The apparatus includes a single cell having a solid polymer electrolyte membrane, power feeders, separators, and fluid channels provided in respective separators. High-pressure hydrogen gas accompanied by water is obtained in the fluid channel by supplying water to the fluid channel and applying current to each power feeder to electrolyze water. The obtained hydrogen gas and water are subjected to gas-liquid separation in a second compartment of a high-pressure vessel, and hydrogen gas thus separated is used to press a barrier member towards the single cell. The separated water is supplied to the fluid channel through the hydrogen gas guide channel.
