GB/T 45331-2025
ActiveePTFE membrane for reinforcement of proton exchange membrane
质子交换膜增强用聚四氟乙烯膜
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging conditions for expanded polytetrafluoroethylene (ePTFE) membranes used as reinforcement layers in proton exchange membranes. It is applied in the manufacturing of fuel cells and electrolyzers, where the ePTFE membrane provides mechanical strength and dimensional stability to the proton exchange membrane under operating conditions. The standard ensures consistent quality for membrane electrode assembly (MEA) production in the hydrogen energy and clean power industries.
