Zusammenfassung:	The effect of the mixed support of carbon black and nanographite (CG) on the electrocatalytic activity and stability of the CG supported Pt (Pt/CG) catalyst for ethanol oxidation was investigated. It was found that the electrocatalytic activity and stability of the Pt/CG catalyst for ethanol oxidation depend on the weight ratio of carbon black and nanographite because the carbon black has a large surface area and nanographite has high conductivity. The Pt/CG catalyst with a weight ratio of 10:1 produces the best electrocatalytic activity and stability of the Pt/CG catalyst for ethanol oxidation.
