Abstract

The invention relates to a method for preparing membrane electrode for solid polymer water electrolyte. It evaporates solid polymer electrolyte solution and forms film, couples catalytic layer composed of catalyst and solid polymer electrolyte on two sides to form integrated membrane electrode, then crystalizes membrane electrode to realize co-crystallization for solid polymer electrolyte. The combination between membrane and catalytic layer is tight and the stratification between membrane and electrode caused by gas evolution and wahsing during water electrolysis process is solved. The invention can produce solid polymer water electrolyte with high performance, high stability and high durability.

Description

Technical field [0001] The invention relates to solid polymer electrolyte water electrolysis, in particular to a method for preparing a novel membrane electrode for solid polymer electrolyte water electrolysis. Background technique [0002] In recent years, with the development of social economy, the supply crisis of fossil energy has emerged. The voice of mankind to protect the earth's environment is increasing. How to develop new energy and efficiently use energy has become the focus of great attention by governments and business circles around the world. As a clean and efficient energy carrier, hydrogen energy is known as the symbol of the 21st century economic era. Electrolyzed water is a very mature technology for preparing high-purity hydrogen and oxygen. At present, alkaline water electrolysis is commonly used, and its disadvantage is that the liquid electrolyte is prone to loss, corrosion and overflow. Solid Polymer Electrolyte (SPE) water electrolysis technology has beco...
