Abstract
Described herein are membrane assemblies for use in generating hydrogen and oxygen. The membrane assemblies include a cation exchange membrane, an anion exchange membrane, and a hydrophilic layer disposed between the anion exchange membrane and the cation exchange membrane.
Claims20
A membrane assembly comprising:
- an anion exchange membrane;
- a cation exchange membrane;
- a hydrophilic layer disposed between the anion exchange membrane and the cation exchange membrane;
- and
- an anion exchange coating disposed between the hydrophilic layer and the anion exchange membrane,
- wherein the hydrophilic layer is laminated to the anion exchange membrane or the cation exchange membrane, and
- wherein the anion exchange coating comprises a catalyst selected from the group consisting of platinum, titanium, iridium, gold, palladium, silver, ruthenium, rhodium, osmium, and combinations thereof.
