Abstract
An MEA preparation method involves low temperature plasma deposition of catalysts such as platinum onto a substrate to form a proton-conducting cation-exchange membrane. The substrate may be a solid polymer electrolyte membrane, or may include carbon cloth or carbon particles. The deposition is carried out at atmospheric pressure without the addition of noble gases to the reactant carrier.
Claims16
A method of manufacturing a proton-conducting cation-exchange electrolyte membrane for use in a membrane electrode assembly (MEA), comprising the step of depositing at least one catalyst layer directly onto a substrate by passing reactants included in a carrier gas through an electrical discharge at atmospheric pressure, wherein said substrate is selected from the group consisting of a polymer membrane, a membrane formed of carbon cloth, and a membrane including carbon particles.
