PFSA Ionomer Membrane,Thickness:50𝜇m,Acid Capacity:1.12 meq/g

Catalog Number	ACMA00062969
Description	This is a perfluorosulfonic acid (PFSA) ionomer membrane that exhibits an equivalent weight (EW) of 870 g/eq. The ionomer membranes are melt-extruded products based on the unique Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F.
Density	1.93 g/cm3 (at 23 deg Celsius and 50% RH. Internal Method.)
Application	The membrane is used to separate the anode and cathode compartment of proton exchange membrane fuel cells (PEMFCs) and water electrolyzers, separators for electrochemical hydrogen pumps or redox flow batteries, and pervaporation or gas humidification systems.
Acid Capacity	greater than 1.12 meq/g (Internal Method)
Feature	Very high concentration of functional groups for strong proton (or Na+, K+, Li+, etc.) conductivity High softening point for high temperature operation well above 80 ºC Strong water retention for better fuel cell operation at low-humidity conditions
Thickness	50 micrometers (or 2 mils)
Type	Cation
