Estudio de degradación acelerada de catalizadores para celdas de combustible de metanol

Abstract

Catalizadores trimetálicos PtMRu/C (M= Co, Fe) tolerantes a la presencia de metanol fueron caracterizados por medio de HRTEM, EDS, XPS y electroquímicamente mediante curvas de polarización y voltamperometría cíclica. Para estudiar su durabilidad y desempeño para la reacción de reducción de oxígeno (ORR) y su tolerancia al metanol en el tiempo, los catalizadores se sometieron a un test electroquímico acelerado de degradación (AST), que consiste en ciclar el potencial 2000 veces. Luego del AST se realizaron curvas de polarización para la ORR en presencia y ausencia de metanol. Luego del AST los catalizadores sintetizados mantuvieron su desempeño para la ORR y la tolerancia al metanol.
