Resumo: The aim of the present study is to assess the potential of ethanol deriving from the mesocarp of babassu coconut to be used in fuel cells. Babassu ethanol was generated through hydrolysis and fermentation processes. The Pt, PtRh and PtRu electrodes were prepared in carbon Vulcan XC72R through the reduction method and applied as electrocatalysts in ethanol oxidation reaction. X-Ray diffraction (XRD), energy-dispersive X-ray (EDX), stripping CO, cyclic voltammetry, chronoamperometry, and online differential electrochemical mass spectrometry (DEMS) were used to characterize the synthesized eletrocatalysts. The electrocatalyst Pt80Ru20/C presented larger active area and higher catalytic activity than other studied materials. The current efficiency of CO2 production rated less than 1% in all studied electrocatalysts, thus showing that babassu ethanol oxidation produces less pollutants than the commercial ethanol.
