Abstract

A method of generating hydrogen water of pH 6 to 8 using at least one electrolyzer (2) is provided. The electrolyzer (2) includes a housing (20), a membrane (25) that partitions the inside of the housing (20), an anode chamber (21) and a cathode chamber (22) that are formed inside the housing by being partitioned by the membrane, an anode (23) that is provided to be in contact with a surface of the membrane at the anode chamber side or provided to be separated from the surface via a small space, and a cathode (24) that is provided to be in contact with a surface of the membrane at the cathode chamber side or provided to be separated from the surface of the membrane at the cathode chamber side via a small space. The method includes continuously supplying the cathode chamber with water that contains a mineral component, supplying the anode chamber with water that does not contain a mineral component of which the amount exceeds an impurity content, applying a DC voltage between the anode and the cathode, and delivering hydrogen water generated in the cathode chamber. This method can generate neutral or alkaline hydrogen water.
