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.

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： In a unit cell that forms a water electrolysis device, which is an electrochemical device, an electrolyte membrane/electrode structure is sandwiched between an anode-side separator and a cathode-side separator. A load-applying mechanism is disposed between a cathode-side feeder and the cathode-side separator, while an anode-side feeder is set with a smaller contact area range than the aforementioned cathode-side feeder. The anode-side feeder and the cathode-side feeder are set with a larger contact area range than an anode electrode catalyst layer and a cathode electrode catalyst layer, and a contact surface that touches a solid polymer electrolyte membrane on the aforementioned anode-side feeder is disposed projecting farther to the side of the aforementioned solid polymer electrolyte membrane than a contact surface on the anode-side separator and a contact surface on a frame member.
