Synthesis of PtLa/C catalysts for polymer electrolyte membrane fuel cells. In: SIMPOSIUM IBERICO DI HIDROGENIO, PILAS DE COMBUSTIBLE Y BATERIAS AVANZADAS, 1., Julio 1-4, 2008, Bilbao. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/16013.http://repositorio.ipen.br/handle/123456789/16013In the present work PtLa/C electrodes have been prepared by an alcohol reduction process to study their activity towards oxygen reduction and methanol and carbon monoxide oxidation. These electrocatalysts were compared to Pt/C in terms of activity and stability using cyclic voltammetry and steady state curves. Results show that PtLa/C materials display higher currents per gram of Pt than Pt/C for the reactions considered. In the case of methanol and CO electro-oxidation, partial removal of the adspecies from the surface takes place at more negative potentials.openAccessdirect methanol fuel cellsplatinum alloyslanthanum alloysmethanoloxidationoxygenreductionTexto completo de eventohttps://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0002-9287-6071
