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