Our proprietary membranes are the most advanced and cost-effective in the world. Here’s why.

Poly(aryl piperidinium) polymers introduce an alkaline-stable cation, piperidinium, into a rigid aromatic polymer backbone that is free of ether bonds. Anion exchange membranes (AEM), or hydroxide exchange membranes (HEM), formed from PiperION® polymers exhibit superior chemical stability, anion conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties.

• December 18, 2020 – Versogen’s electrolyzer technology has been shown to operate at 1,020 mA cm-2 at 1.8 V and with a durability of 160 hours at 200mA cm-2 using a nickel-based anode catalyst and nickel foam porous transport layer. These results have been published in our ACS Catalysis paper.
