Abstract
The electrolysis vessel for alkaline water electrolysis includes an anode end unit, a cathode end unit, anode chamber cells, cathode chamber cells, and separating membranes. The anode/cathode end units each comprise a pressing frame, an insulating plate, and an end cell. The anode/cathode chamber cells are alternately arranged between the anode end unit and the cathode end unit. Electrolyte supply/recovery flow paths are arranged through each chamber cell. Electrolyte supply/recovery pipes each being a metal pipe, at least an inner surface of the metal pipe being coated with an insulating resin, are connected to the electrolyte supply/recovery flow paths respectively via through-holes arranged through the pressing frame(s) and the insulating plate(s). At the junction of the electrolyte supply/recovery pipes and the electrolyte supply/recovery flow paths, electrolytes do not contact with any metal member of the electrolyte supply/recovery pipes or the pressing frames, or any metal member electrically connected therewith.
