Abstract

A precursor electro-catalyst composition for producing a fuel cell electrode. The precursor composition comprises (a) a molecular metal precursor dissolved or dispersed in a liquid medium and (b) a polymer dissolved or dispersed in the liquid medium, wherein the polymer is both ion-conductive and electron-conductive with an electronic conductivity no less than 10S/cm (preferably greater than 10S/cm) and ionic conductivity no less than 10S/cm (preferably greater than 10S/cm). Also disclosed is an electro-catalyst composition derived from this precursor composition, wherein the molecular metal precursor is converted by heat and/or energy beam to form nanometer-scaled catalyst particles and the polymer forms a matrix that is in physical contact with the catalyst particles, coated on the catalyst particles, and/or surrounding the catalyst particles as a dispersing matrix with the catalyst particles dispersed therein when the liquid is removed. The fuel cell comprising such a composition in an electrode exhibits a superior power output.
