The electrocatalysts were characterized by EDX and XRD. The electro-oxidation of ethanol was studied at room temperature by chronoamperometry. PtSn/CeO2–C electrocatalyst with 15 wt% of CeO2 showed a significant increase of performance for ethanol oxidation compared to PtSn/C catalyst. Preliminary tests at 100 °C on a single cell of a direct ethanol fuel cell (DEFC) also confirm the results obtained by chronoamperometry.1315-1317openAccessdirect ethanol fuel cellsoxidationplatinumtincerium oxidescarbonelectrocatalystsalcoholsreductionglycolsArtigo de periódico1010.1016/j.elecom.2008.06.023https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-9287-6071
