Abstract:
1. A precursor electro-catalyst composition for producing a fuel cell electrode, said composition being formed of (a) a molecular metal precursor dissolved or dispersed in a liquid medium and (b) a polymer dissolved or dispersed in said liquid medium; wherein said molecular metal precursor is an organo-metallic compound having at least a carbon-metal bond or a metal organic compound containing at least an organic ligand with a metal-to-non-metal bond, the precursor being convertible by application of heat and/or energy beam to form nanometer-scaled unsupported catalyst particles; and said polymer forms a dispersing matrix that is in physical contact with said unsupported catalyst particles dispersed therein when said liquid medium is removed, and wherein said 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.
