Abstract

A composition comprising particulate carbonaceous material (52) and a conducting polymer containing hetero atoms (54). The composition can further comprise a metal (56). Devices comprising the composition can be constructed including supported electrocatalysts, membrane electrode assemblies, and fuel cells wherein the fuel cells comprise an anode (20), a cathode (50), and a polymer exchange membrane (10). A method for preparing the composition comprises oxidatively polymerizing a monomer of a conducting polymer containing hetero atoms in the presence of a carbonaceous material. The method grafts the conducting polymer to the carbonaceous material. The method can further comprise metallizing the polymer-grafted carbonaceous material.
