Patent ID: 8518225

Claim:
A hydrogen-dissolved drinking water production apparatus, comprising: an electrolytic cell comprising a vertical anode chamber having a water-permeable plate-shaped anode electrode, a vertical cathode chamber having a plate-shaped cathode electrode, a diaphragm of a fluorine-based cation exchange membrane separating the anode chamber and the cathode chamber, and an ion-exchange resin filling a space between the diaphragm and the cathode electrode, wherein the water-permeable plate-shaped anode electrode closely adheres to the diaphragm, and the plate-shaped cathode electrode closely adheres to an inner side wall of the cathode chamber which faces the diaphragm over the space, high-purity water having a conductivity of 50 μS/cm or less is supplied to the electrolytic cell, and water having a pH of 2.5-8.5 and a dissolved hydrogen molecule concentration of 0.1 ppm or more is produced.
