Membrane electrode for hydrogen production by alkaline electrolysis of water and preparation method of membrane electrode

The invention relates to the technical field of electrolyzed water, in particular to a membrane electrode for hydrogen production by alkaline electrolyzed water and a preparation method of the membrane electrode. The membrane electrode comprises a porous diaphragm, and a hydrogen evolution catalyst and an oxygen evolution catalyst which are respectively loaded on two sides of the porous diaphragm, and the porous diaphragm is selected from one of polysulfone, polyether sulfone, polytetrafluoroethylene, polyvinylidene fluoride or polyphenylene sulfide porous membranes. Compared with a traditional separation type diaphragm-Ni net electrode combination, the membrane electrode adopts a thinner polymer porous diaphragm, the overpotential of electrolyzed water is reduced, meanwhile, a catalyst and the diaphragm form a firm binding force and are not prone to falling off, and the stability of the water electrolysis performance of the membrane electrode is improved. 本发明涉及电解水技术领域，具体涉及一种碱性电解水制氢用的膜电极及其制备方法。该膜电极包括多孔隔膜和分别负载
