PROCEDE DE FABRICATION, PAR DEPOT SUR UN SUPPORT, D'ELECTRODE POUR PILE A COMBUSTIBLE

摘要

The method involves alternatively and/or simultaneously depositing porous carbon balls (40) and a catalyst e.g. platinum ball (44), on a support (42) by plasma sputtering. The catalyst accelerates chemical reactions that take place in a fuel cell. Thickness of a layer of porous carbon is selected such that the catalyst deposited on the layer is distributed practically throughout the layer so as to create a catalyzed carbon layer. Independent claims are also included for the following: (1) an electrode (2) a fuel cell comprising an electrode.
