PFSA membranes are often used to separate the anodes from cathodes in electrolysis reactors or fuel cells.
PFSA membranes are polymer 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. 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.
Perfluorosulfonic acid resin is used to makem PFSA membranes. It can also be used adhesive for catalysts.
The manufacturing process enables a homogeneous membrane with even thickness. Perfluorosulfonic acid resin with a suitable molecular weight and ion exchange capacity is used for this. Typically, the membrane is used in chlorine dioxide electrolysis, copper and gold extraction, amino acid processing, caustic soda, electrodialysis and other electrolysis methods.
