<p>There is disclosed a composite membrane and an air electrode for use in hydrogen-oxygen fuel cells, metal-air cells and oxygen sensors. The composite membrane includes a porous membrane having micropores with a thin layer affixed thereto. The thin layer having metallic oxide in a carbon matrix, so that oxygen gas is able to permeate therethrough, but water vapor in air is not allowed to permeate therethrough.</p> |
