Fumapem AM-40 - PBI Copolymer

Fumapem AM-40 - PBI Copolymer

Product Details:


Product Description

Brand: FuMA-Tech
Product Code: 5041632


FumapemAM-40 is a non-reinforced Polybenzimidazole Copolymer membranedesigned for use in High-Temperature Proton Electrolyte Fuel Cells (HT-PEMFC).The polymer backbone for this HT-PEMFC membrane is categorized as a hydrocarbonpolymer material.

FumapemAM-40 membrane comes in either a 10cm x 10cm or 20cm x 30cm size sheet. Themembrane is the brown foil delivered in dry form.


Fumatechmembranes are highly sensitive to differences in humidity and moisture content.Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Alsodue to this sensitivity the manufacturer expects wrinkles to form, howeversoaking the membranes in deionized water will return the membranes to the fullsize planar state according to the manufacturer.


FumapemAM-40 Features:


 Applications: High-Temperature PEM Fuel Cell (HT-PEMFC).
 Thickness: 40 micrometers (1.57 mil)
 Sizes: 10cm x 10cm, 20cm x 30cm



Keep membrane packageclosed / sealed when unused. Store, handle and process the membrane in a cleanand dust-free area. Use only new and sharp knives or blades, when cutting themembrane. Always wear protective gloves when handling the membrane. Handle withcare, be sure not to puncture, crease or scratch the membrane, otherwise leakswill occur. All surfaces in contact with the membrane during handling,inspection, storage and mounting must be smooth and free of sharp projections.


Dopingwith Phosphoric Acid Recommendation:

Put the membrane sample in85 wt % H3PO4 at temperatures between 90C and 160C for at least 1 hour.Membranes must be covered by phosphoric acid. Membranes will expand whensubject to doping process.

If you have any concernsabout storage, chemical stability, pre-treatment or before proceeding, pleasefeel free to contact us for further information.


LongTerm Storage:

Themembrane can be stored dry for an unlimited amount of time. However, themembrane has to be conditioned (washed and rinsed) prior to use.
