Vanadium Ion Redox Flow Battery Proton Exchange Membrane PEM N212
PEM Proton Exchange Membrane PEMFC Polymer Eectrolyte Membrane For Vanadium Redox Battery
N-21 series proton exchange membrane is a single component perfluorinated sulfonic acid H type perfluorinated ion membrane product produced by using the steel strip casting method. Perfluorinated ion membranes are used as solid electrolytes to separate anode and cathode in various electrolytes and batteries
As a solid electrolyte separating anode and cathode in various electrolytic cells and cells, The membrane has the property of one-way passage of cation. Due to the use of polytetrafluorin as the main chain, the most suitable molecular weight and ion exchange capacity can be adjusted, so the membrane has the characteristics of chemical resistance and durability. Widely used in: vanadium cell, liquid flow cell, fuel cell, electrolytic water hydrogen production and other fields.

Packing:
A. coil:
Standard volume: 0.30m*100m
0.61 m * 100 m
0.80 m * 100 m
Special specification: 0.2m/0.3m/0.4m width, arbitrary length. (orders for special specifications should be more than 50 square meters)
B. sheet:
Width: 0.30 m (minimum) to 1 m (maximum)
Length: 0.30 m (minimum) to 1 m (maximum)
Note: film dimensions are based on dry film products before cutting, at 23°C and 50% relative humidity. The humidity and temperature of the air will affect its size. The products that need to be pretreated by our company are guaranteed to be of positive tolerance, and the products that need to be pretreated are all sheet materials.
Film packaging, the use of the volume, less than the volume of no core, a larger number of containing the core. Since the size of perfluorinated ion films will change under different temperature and humidity, perfluorinated ion films are all protected by hard protective film to facilitate the stability of MEA spraying and size reduction. The outer packing is packed in plastic drums or hard cartons.
Please contact the sales staff for special size and packing.
Application:
vanadium cell, liquid flow cell, fuel cell, electrolytic water hydrogen production and other fields.
Packing:
Film packaging, the use of coil, the number of small no core, more volume containing core. As the size of PERfluorinated ion film will change under different temperature and humidity, the perfluorinated ion film is covered with hard protective film to facilitate MEA's spraying and reduce the size stability. The outer packing adopts plastic drum or hard carton packaging.
