Title
(EN) DIRECT AMMONIA-FED SOLID OXIDE FUEL CELL AND METHODS FOR MAKING THE SAME
(FR) PILE À COMBUSTIBLE À OXYDE SOLIDE DIRECTEMENT ALIMENTÉE EN AMMONIAC ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) According to embodiments of the present disclosure, a solid oxide fuel cell includes a cathode, an anode, and a solid oxide electrolyte between the anode and the cathode. The solid oxide electrolyte includes a solid oxide, and the anode includes a porous scaffold. The porous scaffold includes a solid oxide having metal-based catalysts disposed on one or more surfaces of the porous scaffold. In embodiments, at least one ammonia decomposition layer is disposed proximate the surface of the porous scaffold and is configured to convert ammonia into hydrogen and nitrogen for subsequent feed of hydrogen to the anode. The ammonia decomposition layer also includes a metal decomposition catalyst.
(FR) Selon des modes de réalisation de la présente invention, une pile à combustible à oxyde solide comprend une cathode, une anode et un électrolyte à oxyde solide entre l'anode et la cathode. L'électrolyte d'oxyde solide comprend un oxyde solide, et l'anode comprend un échafaudage poreux. L'échafaudage poreux comprend un oxyde solide ayant des catalyseurs à base de métal disposés sur une ou plusieurs surfaces de l'échafaudage poreux. Dans des modes de réalisation, au moins une couche de décomposition d'ammoniac est disposée à proximité de la surface de l'échafaudage poreux et est configurée pour convertir l'ammoniac en hydrogène et en azote pour une alimentation ultérieure d'hydrogène à l'anode. La couche de décomposition d'ammoniac comprend également un catalyseur de décomposition de métal.
