Our Technology


Proton & Cation Exchange Membrane

Pemion™ is the new proton and cation exchange membrane and polymer products (PEM & CEM) in advanced stages of 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 hydrocarbon materials, providing lower gas crossover and eliminating environmental concerns at considerably higher performance.

Unlike their PFSA counterparts, our 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


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.


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


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


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