CATALIZADOR TERNARIO DE PT-RU-ME0X (ME= MO, W,V) SOBRE CARBON CON ALTA TOLERANCIA AL CO EN ANODOS DE PILAS DE COMBUSTIBLE Y SU METODO DE PREPARACION

摘要

The invention tackles the problem associated with deactivating the anode catalysts of fuel cells. The invention relates to a ternary catalyst of Pt-Ru-MeO_X (wherein Me = Mo, W or V) on a carbon support, capable of oxidising CO to CO₂ at potentials above 0.1 V in respect of the normal potential of hydrogen (NHE). The invention also relates to the method for preparing said catalysts, as well as the use thereof as anodes in polymer electrolyte or proton exchange membrane fuel cells supplied with hydrogen obtained from reforming (PEMFC) or direct methanol (DMFC).
