Electrolytic cell for preparing hydrogen-rich water

Abstract

The invention discloses an electrolytic cell for preparing hydrogen-rich water. The electrolytic cell comprises a negative plate, a negative electrode frame, a proton exchange membrane, a positive electrode frame, a positive plate, a negative current collector and a positive current collector, wherein two sides of the proton exchange membrane are respectively coated with a hydrogen evolution catalyst and an oxygen evolution catalyst; the negative electrode frame and the positive electrode frame are of annular structures, are coaxially arranged on two sides of the proton exchange membrane and are used for clamping the proton exchange membrane; the negative current collector is nested in the negative electrode frame, and the positive current collector is nested in the positive electrode frame; a cavity between the negative plate and the positive plate is divided into a negative electrolysis chamber and a positive electrolysis chamber by the proton exchange membrane; a negative electrodewater inlet and a negative electrode water outlet are formed in the negative plate and are respectively used for inputting pure water into the negative electrolysis chamber and outputting hydrogen-rich water; and the positive plate is provided with an positive electrode water inlet and an positive electrode water outlet which are respectively used for inputting pure water and outputting oxygen-containing water into the positive electrolysis chamber.

Description

technical field [0001] The invention relates to the technical field of pure water electrolysis, in particular to an electrolytic cell for preparing hydrogen-rich water. Background technique [0002] Hydrogen-rich water refers to drinking water with a hydrogen content greater than 1mg / L. Studies have found that hydrogen-rich water is effective for a variety of diseases (such as radiation damage in animals, organ ischemia, arteriosclerosis, liver cirrhosis, oxygen toxicity, diabetes, organ and system Inflammation, trauma, Parkinson's disease, senile dementia, carbon monoxide poisoning, etc.) have a good preventive effect. Its mechanism of action is as follows: hydroxyl radicals and nitrite anions are important media of oxidative damage to organisms, and hydrogen dissolved in liquid can selectively neutralize hydroxyl radicals and nitrite anions. In addition, hydrogen has not been found to have toxic side effects on the body. [0003] In the prior art, the preparation methods...

[0003] In the prior art, the preparation methods of hydrogen-rich water mainly include: (1) preparation of hydrogen-saturated water by pure water blowing method, which is the main method used in commercially available bagged or canned hydrogen-rich water; (2) electrolysis of water Generate hydrogen (electrolysis method) into water to prepare hydrogen-rich water, which is the hydrogen production principle of some hydrogen-rich water drinking machines; (3) use the chemical reaction of metal magnesium and water to generate hydrogen (chemical reaction method) to prepare hydrogen-rich water ( The chemical reaction formula for the reaction of metal magnesium and water is: Mg+2H2O=Mg(OH)2+H2↑, which is the principle of hydrogen production by hydrogen rod); among them, the process of producing hydrogen-rich water by pure water blowing method and chemical reaction method Both will have adverse effects on water quality. Relatively speaking, the electrolytic method for producing hydrogen-rich water does not affect water quality in principle, while the electrolytic cell for producing hydrogen-rich water by electrolysis in the prior art cannot produce hydrogen-rich water at one time.
