Title (EN) MULTI-METALLIC ELECTRO-CATALYST FOR ALKALINE EXCHANGE MEMBRANE FUEL CELLS AND METHOD OF MAKING SAME
(FR) ÉLECTRO-CATALYSEUR MULTI-MÉTALLIQUE POUR PILES À COMBUSTIBLE À MEMBRANE ÉCHANGEUSE ALCALINE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Some aspects of the invention may be directed to a catalyst layer for anodes of Alkaline Exchange Membrane Fuel Cells (AEMFC). Such catalyst layer may include catalyst nanoparticles and an ionomer. Each catalyst nanoparticle may include one or more nanoparticles of catalytically active metal supported on at least one nanoparticle of crystalline RuO2. The diameter of the at least one nanoparticle of the crystalline RuO2 may be about order of magnitude larger than the diameter of the one or more nanoparticles of catalytically active metal.
(FR) Certains aspects de l'invention peuvent concerner une couche de catalyseur pour anodes de piles à combustible à membrane échangeuse alcaline (AEMFC). Une telle couche de catalyseur peut comprendre des nanoparticules de catalyseur et un ionomère. Chaque nanoparticule de catalyseur peut comprendre une ou plusieurs nanoparticules de métal catalytiquement actif supportées sur au moins une nanoparticule de RuO2 cristallin. Le diamètre de la ou des nanoparticules de RuO2 cristallin peut être environ d'un ordre de grandeur supérieur au diamètre de la ou des nanoparticules de métal catalytiquement actif.
