Membrane electrode assembly, manufacturing process therefor and direct type fuel cell therewith

摘要

This invention relates to a membrane electrode assembly comprising a fuel electrode, an air electrode and an electrolyte membrane where micropores in a porous membrane is filled with a proton conducting polymer, wherein on at least one side of the electrolyte membrane is formed a planarizing layer, via which a fuel electrode or air electrode is formed, as well as a direct type fuel cell therewith.
