Proton Exchange Membrane (pack of 100) Select grade::Nafion XL The counter (auxiliary) electrode providesProton Exchange Membranes (PEM) are based on chemically stabilized perfluorosulfonic acid PTFE copolymer in the acid (H+) form. The physical properties remain the same for the chemically stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non stabilized polymer a sign of improved chemical durability. Some Proton Exchange Membranes with low thickness are additionally reinforced to maintain mechanical stability.
