Electrocatalysts systems are one of the major concerns in the development of ethanol fuel cells. In this work we synthesized two different systems: PtRuDy and PtU. PtRuDy shows electroactivities similar to Pt3Sn, that is pointed out as the best catalyst for ethanol oxidation. PtU shows a promise result when operated with ethanol and after this with hydrogen and oxygen again. It is well established that electrocatalysts systems as PtRu when operated with alcohols these systems shows a huge degradation when operating with hydrogen again. PtRuDy system shows 46% of degradation while operating with ethanol and turning back to hydrogen. PtU system shows no degradation at all after operating with ethanol 1.0 mol L-1 and turning to hydrogen again.closedAccessfuel cellselectrocatalystsethanol fuelsTexto completo de evento10.4271/2005-01-4078https://orcid.org/0000-0003-0105-6519
