Cation Membrane Variety Kit

Our Cation Membrane Variety Kits consist of one 10cm x 10cm piece of each of the following membranes:

• Nafion 211
• Nafion 212
• Fumapem FS-930
• Fumapem F-1850

Nafion Based Cation Exchange Membranes: Chemours' (formerly DuPont) Nafion membranes are non-reinforced films based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. The physical properties remain the same for the chemically stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer – a sign of improved chemical durability. Nafion PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.

Fumapem and Fumasep Based Cation Exchange Membranes: FuMA-Tech is a leading company for functional membranes and plant technology and is a leading manufacturer of ion exchange membranes for different electrochemical operations. Their modern coating plant produces porous, non-porous and functional membranes with excellent resistance to acids, bases, solvents and oxidation.
