Abstract

The invention discloses a water electrolysis hydrogen production proton exchange membrane and a preparation method thereof.The preparation method of the water electrolysis hydrogen production proton exchange membrane comprises the steps that a vinyl alkaline substance, vinyl phosphoric acid and an initiator are added into a solvent, the temperature condition is 65-85 DEG C, a copolymerization reaction is carried out under the anaerobic condition, and the water electrolysis hydrogen production proton exchange membrane is obtained; the vinyl phosphonic acid and vinyl imidazole copolymer is obtained; carrying out purification treatment on the vinyl phosphonic acid-vinyl imidazole copolymer; the vinylphosphonic acid-vinyl imidazole copolymer, perfluorinated sulfonic acid resin and a dimethylformamide solution which are subjected to purification treatment are prepared into polymer slurry; and coating a microporous reinforced membrane with the polymer slurry, and carrying out drying treatment and heat treatment on the polymer slurry to obtain the proton exchange membrane with the interpenetrating network structure for hydrogen production by electrolysis of water. According to the method, the proton conduction capability of the water electrolysis hydrogen production proton exchange membrane is enhanced, and the performance of the water electrolysis hydrogen production proton exchange membrane on the water electrolysis membrane electrode is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a proton exchange membrane for electrolyzing water to produce hydrogen and a preparation method thereof. Background technique [0002] The electrolytic cell for hydrogen production by electrolysis of water uses water as raw material, and external voltage is applied to form a complete electrification circuit. The injection of electric energy causes the chemical bonds of water molecules to be cracked, hydrogen atoms and oxygen atoms are reconstructed, and finally hydrogen and oxygen are precipitated. Polymer electrolysis system . The main component of the polymer electrolysis system is the membrane electrode, which integrates the proton exchange membrane and the electrode for hydrogen production by electrolysis, greatly shortens the distance between the two electrodes, and effectively reduces the additional power loss caused by the overpotential of the cathode and anode and othe...
