Apparatus and method for producing hydrogen-dissolved drinking water

Abstract

An apparatus for producing in the home hydrogen-dissolved drinking water that is suitable for drinking, has a high dissolved hydrogen concentration, and a long dissolved hydrogen life. A hydrogen-dissolved drinking water production apparatus includes an electrolytic cell through which water can pass for producing drinking water having a pH in a range of 2.5 to 8.5, and in particular, in a range of 5.8 to 8.5, and a dissolved hydrogen concentration of 0.1 ppm or more by supplying high-purity water having a conductivity of 50 μS/cm or less. The hydrogen-dissolved drinking water production apparatus is characterized in that the electrolytic cell includes a vertical anode chamber having a water-permeable plate-like anode electrode and a vertical cathode chamber having a plate-like cathode electrode, the anode chamber and the cathode chamber are separated by a diaphragm formed from a fluorine-based cation exchange membrane, the water-permeable plate-like anode electrode is closely adhered to the diaphragm formed from the fluorine-based cation exchange membrane, and an ion-exchange resin is filled in a space between the diaphragm and the cathode electrode.
