Title
(EN) METHOD FOR SYNTHESIZING AMMONIA USING METAL NANOPARTICLES IN A FUEL CELL
(FR) PROCÉDÉ DE SYNTHÈSE D'AMMONIAC À L'AIDE DE NANOPARTICULES MÉTALLIQUES DANS UNE PILE À COMBUSTIBLE
Abstract
(EN) According to embodiments of the present disclosure, a solid oxide fuel cell includes a cathode, an anode, and a solid oxide electrolyte disposed between the anode and the cathode. The anode includes a porous scaffold that includes a solid oxide having one or more metal nanoparticles disposed on one or more surfaces of the porous scaffold. The porous scaffold and the solid oxide electrolyte are formed from La0.8Sr0.2Ga0.83Mg0.17O2.815 (LSGM), and the metal nanoparticles are selected from the group consisting of platinum, nickel, gold, and combinations thereof. Methods of synthesizing ammonia using the fuel cell are also described.
(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 disposé entre l'anode et la cathode. L'anode comprend un échafaudage poreux qui comprend un oxyde solide ayant une ou plusieurs nanoparticules métalliques disposées sur une ou plusieurs surfaces de l'échafaudage poreux. L'échafaudage poreux et l'électrolyte d'oxyde solide sont formés à partir de La0,8Sr0,2Ga0,83Mg0,17O2,815 (LSGM), et les nanoparticules métalliques sont choisies dans le groupe constitué par le platine, le nickel, l'or et des combinaisons de ceux-ci. L'invention décrit également des procédés de synthèse d'ammoniac à l'aide de la pile à combustible.
