Abstract
(EN) The present invention includes an apparatus, system and method for screening and making one or more electrocatalysts, electrocatalyst arrays, electrodes and catalysts for an oxygen reduction reaction with a Group VIII noble metal in contact with a component-M to form a Group VIII noble metal-component-M-complex, wherein component-M is one or more metals selected from Groups IIIA, IVA, VIII, IB, IIB, VB, VIB, VIIB and WB of the Periodic Table.
(FR) L'invention concerne un appareil, un système et un procédé de recherche systématique et de fabrication d'au moins un électrocatalyseur, une matrice électrocatalytique, une électrode et un catalyseur pour oxydoréduction utilisant un métal noble du groupe VIII en contact avec un composant M afin de former un complexe métal noble du groupe VIII-composant M, le composant M étant au moins un des métaux des Groupes IIIA, IVA, VIII, IB, IIB, VB, VIB, VIIB et WB du tableau périodique des éléments.
