Title
(EN) SEALING GLASS COMPOSITION AND SOLID OXIDE FUEL CELL USING SAME
(FR) COMPOSITION DE VERRE D’ÉTANCHÉITÉ ET PILE À COMBUSTIBLE EN OXYDE SOLIDE L’UTILISANT
(KO) 실링 유리 조성물 및 이를 이용한 고체산화물 연료 전지
Abstract
(EN) The present invention relates to a glass composition available as a sealing material and a solid oxide fuel cell using same. A sealing glass composition according to the present invention comprises 5-30 wt% of SiO2, 3-35 wt% of B2O3, 30-65 wt% of BaO, and 2-20 wt% of CaO and can be properly employed, unlike conventional sealing glass compositions, in a solid oxide fuel cell operating at low and moderate temperatures.
(FR) La présente invention concerne une composition de verre disponible comme matériau d’étanchéité et une pile à combustible en oxyde solide l’utilisant. Une composition de verre d’étanchéité selon la présente invention comprend de 5 à 30 % en pds de SiO2, de 3 à 35 % en pds de B2O3, de 30 à 65 % en pds de BaO, et de 2 à 20 % en pds de CaO et peut être correctement utilisée, contrairement aux compositions classiques de verre d’étanchéité, dans une pile à combustible en oxyde solide fonctionnant à des températures faibles et modérées.
(KO) 본 발명은 실링재로 사용할 수 있는 유리 조성물 및 이를 이용한 고체산화물 연료전지에 관한 것이다. 본 발명에 따른 실링 유리 조성물은 SiO2 5~30 중량%, B2O3 3~35 중량%, BaO 30~65 중량% 및 CaO 2~20 중량%를 포함하여, 종래의 실링재 유리 조성물과 달리 중저온에서 작동하는 고체산화물 연료전지에 적합하게 사용가능한 효과가 있다.
