Title (EN) MULTI-LAYER CATALYST DESIGN
(FR) CONCEPTION DE CATALYSEUR MULTICOUCHE
Abstract:
(EN) The present disclosure relates to improving the performance and/or stability of non-precious metal catalysts in fuel cells and other electrochemical devices. Improved membrane electrode assemblies (MEAs) and fuel cells containing the same are provided. Such MEAs include a catalyst layer made up of at least two sub-layers containing ionomers of differing equivalent weights. The sub-layers may optionally contain mixtures of ionomers. Also provided are methods of making and using the described devices.
(FR) La présente invention porte sur l'amélioration des performances et/ou de la stabilité de catalyseurs en métaux non précieux dans des piles à combustible et d'autres dispositifs électrochimiques. Des ensembles d'électrodes à membrane améliorés (MEA) et des piles à combustible les contenant sont produits. De tels MEA contiennent une couche de catalyseur constituée d'au moins deux sous-couches contenant des ionomères de poids équivalents différents. En option, les sous-couches peuvent contenir des mélanges d'ionomères. L'invention concerne également des procédés de fabrication et d'utilisation des dispositifs selon l'invention.
