PFSA membranes are often used to separate the anodes from cathodes in electrolysis reactors or fuel cells. The thickness of the cation exchange membrane makes the PFSA 130 ideal for methanol fuel cells (DMFC). The PFSA 130 membranes are 127 μm thick and weighs 246 mg/cm².
PFSA 130 membranes are unreinforced films based on chemically stabilized perfluorosulfonic acid / PTFE copolymer in its acid form (H+). The physical properties remain the same for the chemically stabilized membranes. Compared to the unstabilized polymer, these have a much lower fluoride ion release. This means improved chemical resistance. Frontcell™ PFSA membranes are widely used for proton exchange membrane (PEM) in fuel cells and electrolysis reactors. The membrane acts as a separator and solid electrolyte in a variety of electrochemical cells. Typically, such cells require that the membrane selectively carry cations across the cell boundary. The polymer is chemically resistant and durable.
