The electrocatalysts were characterized by EDX, XRD, TEM and cyclic voltammetry. The electro-oxidation of ethylene glycol was studied by cyclic voltammetry and chronoamperometry using the thin porous coating technique. PtSnNi/C electrocatalyst showed a superior performance compared to PtSn/C electrocatalysts in the potential range of interest for direct ethylene glycol fuel cell.2099-2102openAccessalcohol fuel cellsreductionethanol fuelselectrocatalystsplatinumtincarbonnickelArtigo de periódico146210.1016/j.matlet.2007.11.023https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-9287-6071https://orcid.org/0000-0002-7011-8261
