  • Gold-based alloy nanoparticles for use in fuel cell catalysts
    Publication number: 20060178260
    Abstract: A method is featured for fabricating Carbon-supported AuPt nanoparticle catalysts for fuel cells, and particularly fuel cells using methanol as the fuel. The method prepares AuPt-based fuel cell catalysts having a wide range of controllable Au:Pt ratios. The AuPt catalysis are supportable on both carbon black (C) and C/TiO2 support materials. These materials demonstrate electro-catalytic activity towards CO and methanol oxidation, and O2 reduction. The same catalyst material is useful in constructing both anodes and cathodes, and demonstrates bifunctional activity.
