  • Nanostructured PtMcatalyst for PEMFC cells having a high activity and a moderate HOproduction
    Patent number: 9608276
    Abstract: 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.
    Type: Grant
    Filed: January 23, 2014
    Date of Patent: March 28, 2017
    Assignee: Commissariat A L'Energie Atomique Et Aux Energies Alternatives
    Inventors: Alejandro Franco, Rodrigo Ferreira de Morais, David Loffreda, Philippe Sautet
