Abstract

PtRu(1:1)/C catalysts were prepared by a process that was claimed previously to lead to nonalloyed Pt and Ru particles, using twodifferent precursors, Ru nitrosyl nitrate and Ru chloride hydrate. Both X-ray diffraction and characterization by cyclic voltammetrypoint toward Pt and Ru being present as separate phases in the prepared, nonannealed catalysts. In combination with a highdispersion, this results in proton exchange membrane fuel cell (PEMFC) anode electrocatalysts. These PEMFCs have improvedhydrogen oxidation activity and CO tolerance.
