Abstract
Ways of making electrodes and electrodes produced thereby are provided. Dry blending of a powder mixture including a catalyst, an ionomer, and a polyether forms a blended mixture, which can be comminuted to obtain a desired particle size. A slurry of the blended mixture is formed with an aqueous medium and the slurry is coated onto a substrate to form a coated substrate. The coating can be transferred to another substrate or material for use as an electrode and/or the substrate of the coated substrate can form part of a structure, such as a membrane electrode assembly for use in a fuel cell.
