Apparatus for producing electrolytic water
First Claim
1. An apparatus for producing electrolytic water comprising a two-chamber electrolytic cell partitioned by a diaphragm into an anode chamber having a gas- and liquid-permeable anode and a cathode chamber having a gas- and liquid-permeable cathode, said diaphragm comprising at least two ion-exchange membranes in intimate contact with each other or comprising at least two ion-exchange membranes and a metal foil intimately sandwiched between two of the ion-exchange membranes, and wherein the anode and the cathode are disposed on opposing sides of said diaphragm.

Abstract
An apparatus for producing electrolytic water in which the yielded electrolytic water does not suffer quality deterioration caused by chemical species, e.g., hydrogen ions, moving to the counter-electrode chamber. A diaphragm 4 of a two-chamber type electrolytic cell comprises two or more ion-exchange membranes 3, and a noble-metal layer 2 or another layer may be formed in the diaphragm. Use of the ion-exchange membranes produces an enhanced physical screening effect, while formation of the noble-metal layer produces catalytic effect to decompose chemical species. Both the ion-exchange membranes and the anode-metal layer are effective in diminishing the movement of chemical species to the counter-electrode chamber.

21. A method for producing electrolytic water which comprises:
-
providing a two-chamber electrolytic cell partitioned by a diaphragm into an anode chamber having a gas- and liquid-permeable anode and a cathode chamber having a gas- and liquid-permeable cathode, said diaphragm comprising at least two ion-exchange membranes in intimate contact with each other or comprising at least two ion-exchange membranes and a metal foil intimately sandwiched between two of the ion-exchange membranes, and wherein the anode and the cathode are disposed on opposing sides of said diaphragm, supplying pure water to the anode and cathode chambers, passing an electric current through the electrolytic cell to produce by electrolysis anode water in the anode chamber and cathode water in the cathode chamber, said electrolysis generating hydrogen ion in the cathode chamber and hydroxyl ion in the anode chamber, and said diaphragm preventing hydroxyl ion generated in the anode chamber from entering the cathode chamber and preventing hydrogen ion generated in the cathode chamber from entering the anode chamber, and recovering anode water and cathode water from the electrolytic cell. - View Dependent Claims (22, 23)
