Abstract

A method for the production of an electrode for a fuel cell is provided that comprises providing a multitude of catalyst particles carried on at least one electrically conductive particle carrier, and depositing one or more atomic or molecular layers of an ionomer from the gas phase on the catalyst particles and/or the at least one particle carrier, thereby forming a proton-conducting ionomer coating. Furthermore, an electrode for a fuel cell is also provided.
