Fumasep FAP-450 - 356cm²

Fumasep FAP-450 is a non-reinforced Fluorinated Anion Exchange Membrane (AEM) with low resistance, high blocking capability of vanadium ions, and high stability in acidic environment. The polymer backbone for this AEM is based on a hydrocarbon polymer material. FAP-450 membrane is manufactured on the PET cover film in order to prevent damages to the membrane during its shipment.  The PET foil is located only on one side of the FAP-450 membrane and it needs to be removed from the membrane surface before testing or using the membrane.  FAP-450 is transparent and more flexible than the PET cover film.  The membrane is ready for use when it arrives.

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.

 • Applications: Redox-Flow Battery, e.g. Vanadium-Redox-Flow Battery (VRB), using aqueous acidic conditions.
 • Anion Exchange Membrane
 • Thickness: 50 micrometers (1.97 mil)

Acidic environment pH < 4, at pH > 4 the material has low ionic conductivity. The material is not stable in caustic environment (pH > 11). General temperature range is room temperature to 50°C.
