Dioxide Materials: The Source For Anion Exchange Membrane Water Electrolyzers

At Dioxide Materials, we have developed unique alkaline membranes that when combined with non-precious catalysts, provide a more cost- effective platform for water electrolysis, enabling low-cost solutions for the hydrogen economy. Whether you're looking for a specific component or an entire system, we can help you find a suitable solution.

Dioxide Materials™ offers Sustainion® anion exchange membranes, enabling alkaline water electrolyzers with up to 2.3 A/cm² current at 2.0 V with base metal catalysts at 60 degrees Celsius. Research grade anion exchange membrane water electolyzers, new PTFE Supported Sustainion®37-50 Alkaline Exchange Membranes with reinforced support for easier handling and better mechanical strength, electrodes and catalysts are all available for sale.

Our water electrolyzer includes corrosion resistant 5 cm² anode and cathode flow fields, an MEA with base metal catalysts, metal gas diffusion layers, o-ring seals, and Teflon gasketing. The electrolyzer is designed to be run with 1 M KOH flowing on the anode and cathode as described in Zengcai Liu et al. " The effect of membrane on an alkaline water electrolyzer" International Journal of Hydrogen Energy, 42 29661-29665 2017.
