Dioxide Materials’ Patent on Catalyst Layers & Electrolyzers Issues in Australia

Dioxide Materials is paving the way to cost-effective routes to sustainable chemicals and fuel production.

Dioxide Materials’ Australian Patent Number 2016401931 describes the granted claims of U.S. application Serial No. 15/158,227, which issued as U.S. Patent No. 9,945,040 on April 17, 2018. This patent claims the use of ionomers containing cyclic amines for fuel cells and, CO₂ and water electrolyzers.  Dioxide Materials had previously shown that ionic liquids containing cyclic amines can be used to enhance electron transfer in CO₂ and water electrolyzers thus lowering the overpotential for CO₂ and alkaline water electrolysis.  This patent shows that the cyclic amine can be in the form of a polymer with styrene and paves the way to more cost-effective routes to sustainable chemicals and fuels production.

Dioxide Materials has developed research grade electrolyzers, Sustainion membranes and ionomers, as well as electrodes and cell components.  For more information, please visit www.dioxidematerials.com.
