Title: Membrane electrode assembly manufacturing process

Abstract

A method of making a component of a membrane electrode assembly comprising the steps of forming an electrode on an air-permeable backer comprising ePTFE, depositing a mixture comprising ionomer and a water-insoluble alcohol onto said electrode, drying said mixture to form a protective ionomer layer, and depositing an ePTFE-reinforced ionomer layer onto said protective ionomer layer.
