This patent claims the use of ionomers containing cyclic amines for fuel cells and, CO₂ and water electrolyzers.  We 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.
