  • Method for producing a fuel cell electrode, involving deposition on a support
    Patent number: 8956509
    Abstract: The invention relates to a method for producing carbon electrodes by deposition on a substrate, to produce a fuel cell. The method comprises the steps of alternately and/or simultaneously depositing porous carbon and a catalyst onto the substrate by plasma spaying in a vacuum chamber. The catalyst is used to accelerate at least one of the chemical reactions that takes place in the fuel cell. The thickness of each layer of porous carbon is chosen so that the catalyst deposited on this carbon layer is distributed essentially throughout this layer, thereby by providing a layer of catalyzed carbon. The total thickness of catalyzed carbon in the electrode is less than 2 micrometers, and preferably equal to no more than 1 micrometer.
