Next, since the human body is mostly made of acid, it is desirable to drink weakly alkaline water to neutralize it. In addition to the neutralizing effect, weak alkaline water is known to inhibit cancer, help the activity of antioxidants and enzymes in the body, and also help strengthen immunity by improving digestion and absorption of food.

Hydrogen-containing water not only can exert the above-mentioned effects, but also when the problem of radioactive contamination in the body due to radiation leakage at the time of the Fukushima nuclear accident in Japan in 2011 emerged as a serious social problem internationally, the hydrogen-containing water also has a radioactive detoxification effect. As this was revealed, the increase in the international community's demand for hydrogen-containing water is rapidly accelerating.

Hydrogen-containing water can convert active oxygen in the body into water to be absorbed into the body or discharged out of the body. Specifically, since hydrogen can pass through the cell membrane, it can combine with harmful active oxygen in the cell, and the active oxygen combined with hydrogen can be converted into water. Therefore, it is a reality that hydrogen-containing water has been found to have excellent effects on various diseases such as cancer, diabetes, and cerebral infarction caused by excessive free radicals in the body, and thus is receiving more attention.

The ion exchange membrane does not pass water but can pass cations, such as hydrogen ions (H+).

The ion exchange membrane 141 may be a cation exchange membrane.

The ion exchange membrane 141 may close the connection passage 130 between the electrolyzer 110 and the water storage tank 120 . Therefore, blocked by the ion exchange membrane 141 , the water accommodated in the second accommodation space 122 cannot move to the first accommodation space 111 , and the water accommodated in the first accommodation space 111 is transferred to the second accommodation space. You cannot move to (122).
