Resumen: Ethanol is an alternative choice as a fuel in a direct combustion fuel cell. Its non toxicity and its availability from biomass resources advocate its use in a direct ethanol fuel cell (DEFC), even if the actual performance obtained are slightly lower than those observed with methanol. By modifying the composition of the platinum anode by adding tin, it was confirmed that the overall electrocatalytic activity is greatly enhanced at low potentials. The optimum composition in tin is in the range 10-20 at.
