Abstract

The electrooxidation of methanol on a novel carbon supported PtRu electrocatalyst produced via colloidal PtRu precursors was investigated by thin-film-electrode (TFE) measurements and compared with commercially available Pt and PtRu catalysts. The PtRu-colloid-based catalyst shows similiar activity towards methanol oxidation as other conventional PtRu catalysts. A comparison with literature data from half-cell measurements at similiar mass-specific current densities clearly demonstrates the high potential of the colloid-based PtRu catalyst for fuel-cell applications.
