Proton Exchange Membranes and Polymers replacing fluorinated polymers (PFCs)


Ionomr has developed an ion-conductive membrane with the broadest chemical and mechanical stability available. The membranes are made from hydrocarbon polymers without any PFCs added. The most widely-used membranes today are perfluorinated and these are non-recyclable and generates bio-accumulative toxic waste. The hydrocarbon-based materials include Pemion™, a high-performance proton-exchange membrane (PEM) product suitable for the next generation of PEM-based hydrogen fuel-cells on the market. 


Pemion™ is an advanced, non-toxic proton exchange membrane (PEM) that offers higher performance and efficiency, massively reduced gas crossover, and improved recyclability compared to traditional PEM alternatives. The use of hydrocarbon materials reduces environmental and supply concerns of fluorinated materials while offering increased performance, operating temperature, recyclability, fuel efficiency, and durability as a result of reduced gas crossover.

Pemion is designed for longer lifetimes, particularly for heavy duty applications, as well as lower resistance, reduced precious metal degradation, enhanced efficiency at low loadings, and lower gas permeability for reduced chemical stress and hydrogen wastage in real systems.
