Direct methanol fuel cells are increasingly considered as an attractive power source for mobile applications because of the high energy density. The binary PtRu nanoparticle catalyst on carbon support is currently one of the most-studied electrocatalysts showing a bifunctional catalytic mechanism. A systematical electrochemical characterization of PtRu/Vulcan carbon catalysts (E-tek) for methanol oxidation under various conditions was carried out. The results revealed some initial insights into the experimental conditions for comparing the catalytic activities of different electrocatalysts. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
