NANOSTRUCTURED PTXMY CATALYST FOR PEM FUEL CELLS HAVING A HIGH ACTIVITY AND A MODERATE H2O2 PRODUCTION

摘要

A method of manufacturing a catalyst for a PtxMy-based PEMFC, M being a transition metal, including the steps of: depositing PtxMy nanostructures on a support; annealing the nanostructures; depositing a PtxMy layer at the surface of the nanostructures thus formed; and chemically leaching metal M. It also aims at the catalyst obtained with this method.
