Reinforced PFSA membrane Nafion NC700

PEM membrane is based on chemically stabilized perfluorosulfonic acid (PFSA)/polytetra- fluoroethylene (PTFE) copolymer in the acid (H+) form, which is reinforced and exhibits substantially lower fluoride ion release compared to non-stabilized polymers—a sign of improved chemical durability.

Proton exchange membrane NC700 mainly as a MEA (Membrane electrode assembly) for PEM hydrogen fuel cell membrane. With the extremely thin thickness of 15 microns, the PEM membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the PEM membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.

1.How should this PEM membrane handling practices？

Ventilation should be provided for safe handling and processing of Nafion PFSA membrane. The amount of local exhaust necessary for processing Nafion PFSA membrane at elevated temperatures will depend on the

combined factors of membrane quantity, temperature, and exposure time.

2.How to dispose of waste materials？

Preferred disposal options are recycling and landfill. Incinerate only if incinerator is capable of scrubbing out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable federal, state/provincial, and local regulations.

3.How to discharge this Nafion NC700 membrane？

In dust- or solvent-laden air, a flash fire or explosion could follow. Extreme caution is needed to prevent static accumulation when using flammable solvents while coating membrane surfaces. Solvent-coating equipment should incorporate the means for detecting and extinguishing fire.
