The present invention provides a low-temperature method for producing electrocatalytic coatings for fuel cell electrodes. The electrocatalytic coating comprises a thin-film of diamond-like carbon doped with finely-dispersed catalytic agent, preferably platinum, platinum-ruthenium, or other catalytically active materials. The method may be scaled-up as a highly economical reel-to-reel process comparable to the manufacture of coated polymers for food packaging applications.

A method for forming an electrocatalytic coating for a fuel cell electrode comprising: placing a substrate in a vacuum chamber; vaporizing a diamond-like carbon precursor and a catalytic agent to form a flux comprising a vaporized mixture of said precursor and said catalytic agent; condensing said flux onto said substrate in a vacuum for a time sufficient to form a film of said flux on said substrate and at a temperature low enough to avoid damaging said substrate; substantially simultaneously bombarding said substrate with an energetic beam of ions at an energy, a density, and for a time sufficient to form an electrocatalytic coating on said substrate.
