PFSA membranes are often used to separate the anodes from the cathodes in electrolysis reactors or fuel cells. The thickness of the cation exchange membrane makes the PFSA 50 ideal for hydrogen fuel cells. The Frontcell™ PFSA 50 membrane is 51 µm thick and weighs 102 mg/cm².
Frontcell™ PFSA 50 membranes are unreinforced films based on chemically stabilized perfluorosulfonic acid / PTFE copolymer in its acid form (H+). The physical properties of the chemically stabilized membranes remain the same. Compared to the unstabilized polymer, these have a significantly lower fluoride ion release. That means improved chemical resistance. Frontcell™ PFSA membranes are widely used for proton exchange membranes (PAM) in fuel cells and electrolysis reactors. The membrane acts as a separator and solid electrolyte in a large number of electrochemical cells. Typically, such cells require that the membrane selectively transport cations across the cell boundary. The polymer is chemically resistant and durable.
