Abstract
(EN)
The present invention relates to a glass composition capable of being used as a sealant, and a solid oxide fuel cell using same. The sealant glass composition according to the present invention comprises 10-45 wt% of SiO2, 0.1-20 wt% of B2O3, 40-65 wt% of BaO, 0.1-20 wt% of CaO, and 0.1-15 wt% of at least one of Al2O3 and ZrO2, and unlike existing sealant glass compositions, can be suitably used in solid oxide fuel cells operating at intermediate temperatures, and exhibits an advantageous effect in keeping a decrease in sealing adhesion strength to a minimum, even after prolonged use.
(FR)
La présente invention concerne une composition de verre pouvant être utilisée comme matériau d’étanchéité, et une pile à combustible à oxyde solide l’utilisant. La composition de verre d'étanchéité selon la présente invention comprend de 10 à 45 % en poids de SiO2, de 0,1 à 20 % en poids de B2O3, de 40 à 65 % en poids de BaO, de 0,1 à 20 % en poids de CaO et de 0,1 à 15 % en poids d'Al2O3 et/ou de ZrO2, et à la différence des compositions de verre d'étanchéité existantes, cette composition peut être utilisée de manière appropriée dans des piles à combustible à oxyde solide fonctionnant à des températures intermédiaires, et présente un effet avantageux en maintenant une baisse de la force d'adhérence d'étanchéité à un minimum, même après une utilisation prolongée.

본 발명은 실링재로 사용할 수 있는 유리 조성물 및 이를 이용한 고체산화물 연료전지에 관한 것이다. 본 발명에 따른 실링 유리 조성물은 SiO2 10~45 중량%, B2O3 0.1~20 중량%, BaO 40~65 중량%, CaO 0.1~20 중량%, SrO, Al2O3 및 ZrO2 가운데 1종 이상 0.1~15 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.
