Abstract
(EN)
The present invention relates to: a glass composition that can be used as sealing material; and a solid oxide fuel cell using same. A sealing glass composition according to the present invention includes 10-35 wt% of SiO2, 3-35 wt% of B2O3, 30-65 wt% of BaO, 0.1-15 wt% of CaO, 0.1-3 wt% of NiO, and 0.1-3 wt% of CuO. Unlike conventional glass compositions as sealing material, the present sealing glass composition is suitable for use in solid oxide fuel cells that operate at medium-low temperatures, and in particular, has the excellent effect of minimizing sealing adhesion strength degradation even after long-term use.

La présente invention concerne une composition de verre apte à une utilisation comme matériau d'étanchéité et une pile à combustible à oxyde solide l'utilisant. Une composition de verre d'étanchéité selon la présente invention comprend 10 à 35 % en poids de SiO2, 3 à 35 % en poids de B2O3 , 30 à 65 % en poids de BaO, 0,1 à 15 % en poids de CaO, 0,1 à 3 % en poids de NiO, et 0,1 à 3 % en poids de CuO. Contrairement aux compositions de verre classiques utilisées comme matériau d'étanchéité, la présente composition de verre d'étanchéité est appropriée pour être utilisée dans des piles à combustible à oxyde solide qui fonctionnent à des températures moyennes-basses, et en particulier, présente l'excellent effet de réduire au minimum la dégradation de la force d'adhérence d'étanchéité même après une utilisation à long terme.

본 발명은 실링재로 사용할 수 있는 유리 조성물 및 이를 이용한 고체산화물 연료전지에 관한 것이다. 본 발명에 따른 실링 유리 조성물은 SiO2 10~35 중량%, B2O3 3~35 중량%, BaO 30~65 중량%, CaO 0.1~15 중량%, NiO 0.1~3 중량% 및 CuO 0.1~3 중량%를 포함하여, 종래의 실링재 유리 조성물과 달리 중저온에서 작동하는 고체산화물 연료전지에 적합하게 사용 가능하고 특히 장기간 사용 후에도 실링 접착강도의 저하가 최소화되는 우수한 효과가 있다.
