  • MEMBRANE ELECTRODE ASSEMBLY FOR WATER ELECTROLYSIS, WATER ELECTROLYSIS CELL INCLUDING THE MEMBRANE ELECTRODE ASSEMBLY AND METHOD FOR FABRICATING THE MEMBRANE ELECTRODE ASSEMBLY
    Publication number: 20230366113
    Abstract: Disclosed are a membrane electrode assembly for water electrolysis, a water electrolysis cell including the membrane electrode assembly, and a method for fabricating the membrane electrode assembly. An anion exchange membrane of the membrane electrode assembly for water electrolysis includes a polymer having a stable backbone without aryl ether linkages and containing piperidinium groups with high chemical stability and phenyl-based blocks with excellent mechanical properties introduced therein. Due to its structure, the polymer has improved alkaline stability and processability and excellent mechanical properties, based on which the durability of the membrane electrode assembly can be improved. Therefore, the membrane electrode assembly for water electrolysis can be used to manufacture a water electrolyzer with high current density, low resistance, and improved life characteristics.
