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.

Benefits of the Pemion™ Material

Stable

Chemically and oxidatively stable showing essentially zero degradation when subjected to radical attack in the Fenton test for one hour at high temperatures, 80⁰C.

High Strength

Strongest unsupported materials on the market for ease of handling, longer life and thinner membranes, resulting in low ionic resistance.

Performance

High conductivity at both room and elevated temperatures to enable low resistance applications with higher current densities.

Processable

Soluble polymer in low-boiling solvents, allowing simple and consistent integration into existing product platforms as a strong industrial coating.Can be used as a stable, ion-conductive catalyst binder and enables coated, 3D electrodes.

Green

Drastically reduces the environmental impact of your product throughout its entire lifecycle in comparison to leading PFSA materials.
