T/SDMS 005-2021 Proton exchange membrane used for hydrogen fuel cell made of polytetrafluoroethylene-based membrane

Scope

Scope: This document specifies the terms and definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for polytetrafluoroethylene-based membranes used in proton exchange membranes for hydrogen fuel cells. This document applies to polytetrafluoroethylene membranes that play a supporting and reinforcing role in proton exchange membranes for hydrogen fuel cells. Main technical content: Developing high-strength PTFE base membranes with uniform strength, uniform thickness, and uniform pore size. The thickness of the membrane base material should be uniform (with a tolerance of within 0.01 micrometers), the pore size should be uniform (with a tolerance of within 0.01 micrometers), and the strength should be uniform. These three factors are key to ensuring that the stretched membranes meet international standards.
