Abstract:
1. A method of making a membrane electrode assembly comprising: casting onto a nonporous release surface a solvent ink layer comprising a volatile solvent, a catalyst, an electrically conductive particulate material, and an ionomer binder; disposing a porous releasable decal over the solvent ink layer; drying to remove the volatile solvent from the solvent ink layer to form an electrode layer, peeling off the electrode layer and the decal together from the nonporous release surface; providing a polymer electrolyte membrane having two sides; pressing the electrode layer and the decal together against at least one of the sides of the membrane with the electrode layer in intimate contact with the membrane, causing the electrode layer to bond securely onto the membrane; and removing the releasable decal from the electrode layer.
