Title
(EN) FUEL CELL CATALYST SUPPORT WITH BORON CARBIDE-COATED METAL OXIDES/PHOSPHATES AND METHOD OF MANUFACTURING SAME
(FR) SUPPORT DE CATALYSEUR DE PILE À COMBUSTIBLE À OXYDES/PHOSPHATES MÉTALLIQUES REVÊTUS DE CARBURE DE BORE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) A fuel cell catalyst support includes a support structure having a metal oxide and/or a metal phosphate coated with a layer of boron carbide. Example metal oxides include titanium oxide, zirconium oxide, tungsten oxide, tantalum oxide, niobium oxide and oxides of yttrium, molybdenum, indium, and tin and their phosphates. A boron carbide layer is arranged on the support structure by a chemical or mechanical process, for example. Finally, a catalyst layer is deposited on the boron carbide layer.
(FR) L'invention porte sur un support de catalyseur de pile à combustible qui comprend une structure de support présentant un oxyde métallique et/ou un phosphate métallique revêtu d'une couche de carbure de bore. Des exemples d'oxydes métalliques comprennent l'oxyde de titane, l'oxyde de zirconium, l'oxyde de tungstène, l'oxyde de tantale, l'oxyde de niobium et des oxydes d'yttrium, de molybdène, d'indium et d'étain, et leurs phosphates. Une couche de carbure de bore est agencée sur la structure de support par un procédé chimique ou mécanique, par exemple. Enfin, une couche de catalyseur est déposée sur la couche de carbure de bore.
