ePTFE Reinforced PFSA Membrane (12 microns thick) for PEM Fuel Cells

Catalog Number	ACMA00062939
Description	ePTFE Reinforced PFSA Membrane for PEM Fuel Cells is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form. Chemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated. Chemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin. Functional groups for this PFSA membrane are based on the long side chain for its chemical structure.
Application	ePTFE Reinforced PFSA Membrane for PEM Fuel Cells is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2/Air as the fuel/oxidant and requires achieving high current densities.
Elongation At Break	> 100% / 100% (MD/TD) (per GB/T20043.2022)
Feature	Because the ePTFE reinforcement absorbs the stresses associated with expansion, its service life is significantly extended.
