In StockNafion Membrane -N117/115/212/211/NC700 Perfluorinated Sulfonic Acid ion Membran
In the field of proton exchange membranes (PEMs), the most commonly commercialized PEM membrane is Chemours' (formerly DuPont) Nafion membrane. This is a proton conductive polymer membrane, also known as a perfluorosulfonic acid membrane, which allows protons (cations) to pass through, hence it is also known as a cation exchange membrane (CEM).
It is suitable for electrolyte diaphragm in fuel cell, vanadium cell, electrolytic cell, electrodialysis and electrochemical sensor
