The Standardization Administration of China (SAC) recently announced the approval and release of 273 recommended national standards, which included 'Proton Exchange Membrane for Hydrogen Production by Water Electrolysis.' This standard is set to become effective on September 1, 2025. The document outlines the classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage guidelines for proton exchange membranes used in hydrogen production through water electrolysis. It is designed to be applicable to the research, production, use, and management aspects of proton exchange membranes within water electrolysis systems. This move is expected to significantly impact the hydrogen production industry in China by promoting standardization and quality control measures. Overall, the introduction of this national standard is a positive development aimed at improving the efficiency and reliability of proton exchange membranes in hydrogen production processes.
