PFSA/ePTFE Reinforced Proton Exchange Membrane,Thickness:30𝜇m

Catalog NumberACMA00062996

CategoryProton Exchange Membranes

Description	This is an unreinforced PFSA membrane and it is manufactured via extrusion melt process. The Proton Exchange Membrane 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	The Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM water electrolyzers because of its relatively thick nature and robustness compared to other thinner PFSA membranes.
Elongation At Break	> 150% / 150% (MD/TD) (ASTM D882, 25 deg C, 50% RH)
Feature	The mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method. The major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling-related stresses being taken up by the ePTFE reinforcement.
