Fumasep FAP-330 is a fluorinated anion-exchange membrane - non-reinforced with low resistance, high blocking capability of vanadium ions, and high stability in acidic environment.

Fumasep FAP-330 membrane comes in either a 10cm x 10cm or 20cm x 30cm size sheet.

Fumatech membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Also due to this sensitivity the manufacturer expects wrinkles to form, however soaking the membranes in deionized water will return the membranes to the full size planar state according to the manufacturer.

Fumasep FAP-330 Features:
 

Applications: Redox-Flow Battery, e.g. Vanadium-Redox-Flow Battery (VRB), using aqueous acidic conditions. Another application that can benefit greatly from this membrane is non-aqueous redox flow batteries that utilize organic solvents such as acetonitrile, etc. The dimension change or swelling of the membrane for non-aqueous redox flow battery applications would predominantly depend on the chemical composition of the electrolyte used. Mechanically reinforced fluorinated anion exchange membranes would demonstrate increased mechanical stability and lower solvent mediated crossover compared to non-reinforced counterparts for non-aqueous redox flow battery applications.
Type: Anion Exchange Membrane
Operation Range: Acidic environment pH < 4, at pH > 6 the material has low ionic conductivity. The material is not stable in caustic environment (pH > 9). General temperature range is room temperature to 50 °C.
Thickness (dry): 27 – 33 micrometers (1.06 - 1.29 mil)
Sizes: 10cm x 10cm, 20cm x 30cm

Fumasep FAP-330 Technical Specification Sheet

Delivery:

The membrane is the transparent foil. The membrane is ready to use.

Handling:

Keep membrane package closed / sealed when unused. Unpack membrane only for direct use and process immediately after opening. Store, handle and process the membrane in a clean and dust-free area. Use only new and sharp knives or blades, when cutting the membrane. Always wear protective gloves when handling the membrane. Handle with care, be sure not to puncture, crease or scratch the membrane, otherwise leaks will occur. All surfaces in contact with the membrane during handling, inspection, storage and mounting must be smooth and free of sharp projections.

Pre-Treatment and Conditioning:

The membrane is delivered in dry form. No pretreatment is required. However, membranes will expand and contract based on electrolyte content. If you have any concerns about storage, chemical stability, and pretreatment please feel free to contact us for further information.
