Nafion membranes are often used to separate the anodes from cathodes in electrolysis reactors or fuel cells. The thickness of the cation exchange membrane makes Nafion™ 117 ideal for methanol fuel cells (DMFC). Nafion™ 117 is 183 μm thick.
Chemours™ (formerly DuPont™) Nafion™ 117 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. Nafion™ 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.
