Abstract
A composite electrolyte membrane for a fuel cell is disclosed. The membrane is formed of a polymer having layers of a clay-based cation exchange material. The substrate comprises an electrode formed from a solution that has an exfoliated, inorganic, sodium-based cation exchange material, an ionically conductive polymer-based material, and a solvent-dispersant.
