Patent ID: 8318385

Claim:
A process for producing a fuel cell electrode, said process comprising: (a) preparing a first suspension or solution comprising the sequential steps a first liquid medium, a first molecular metal precursor with no particulate support material, and a first polymer dissolved or dispersed in said first liquid medium; (b) dispensing said first suspension or solution onto a first primary surface of a substrate selected from a first electronically conductive catalyst-backing layer or a solid electrolyte membrane; and (c) converting said first molecular metal precursor to catalyst particles and removing said first liquid medium to form a first electrode connected to or integral with said substrate, wherein said first polymer is both ion-conductive and electron-conductive with an electronic conductivity no less than 10 −4 S/cm and ionic conductivity no less than 10 −5 S/cm and said polymer forms a coating in physical contact with said catalyst particles or coated on said catalyst particles.
