The electrocatalysts were characterized by energy-dispersive X-ray analysis, X-ray diffraction, and transmission electron microscopy. The electro-oxidation of ethanol was studied by cyclic voltammetry chronoamperometry at room temperature and on a single cell of a direct ethanol fuel cell at 100 °C. Cyclic voltammetry and chronoamperometry experiments showed that PtSnRh/C and PtSn/C electrocatalysts have similar performance for ethanol oxidation at room temperature, while the activity of PtRh/C electrocatalysts was very low. At 100 °C on a single cell, PtSnRh/C showed superior performance compared to PtSn/C and PtRh/C electrocatalysts.91-95openAccesselectrocatalystsplatinumtinradiumcarbonalcoholsreductionglycolsethanoloxidationfuel cellsx-ray diffractiontransmission electron microscopyArtigo de periódico11610.1007/s11581-009-0396-3https://orcid.org/0000-0002-9287-6071https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-7011-8261
