Multi-functional support
The present invention provides TixMyO2 (M: Ru, Mo or other metals; x, y are positive numbers) as the carbon-substituted support for Pt (or other catalysts) in fuel cells. The Pt/TixMyO2 can be employed as an anodic catalyst for methanol oxidation or as a cathodic catalyst for oxygen reduction in DMFC, depending on the formula and composition of support. The novel TixMyO2 catalyst support material is to resolve the corrosion problem of carbon support which has been one of the major hurdles for commercialization of this technology.
