  • Diamond-like carbon based electrocatalytic coating for fuel cell electrodes
    Patent number: 5624718
    Abstract: 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.
