Pemion™
Durable, High Performance Cation Exchange
Pemion™ is a breakthrough proton exchange membrane (and cation exchange) and polymer product (PEM & CEM) in advanced development at Ionomr.
Pemion represents a fundamental shift in the approach to proton exchange technology through its migration from Perfluorinated Sulfonic Acid (PFSA) chemistry to environmentally-benign hydrocarbon materials while maintaining maximum durability.These hydrocarbon materials also provide considerably higher performance, lower gas crossover and eliminate environmental concerns associated with End-of-Life (EOL) disposal of fluorinated compounds.
The resulting gains in performance and reductions in gas crossover provide a revolutionary impact on hydrogen fuel cell cost through reduction in precious metal usage, longer lifetimes through reduced degradation and higher efficiency by operating at higher temperature with less fuel crossover.Other applications impacted by this technology are advanced battery technologies including electrodes, coatings and solid electrolytes.
Unlike their PFSA counterparts, Ionomr’s hydrocarbon products have substantially reduced toxicity and environmental impact during both manufacturing and disposal.Additionally, Pemion boasts one of the highest room temperature conductivities available, while maintaining its mechanical stability (Adamski et al., Angew. Chem. Int. Ed. 2017, 56, 1 – 5) for an improved total efficiency and longer system life.
