摘要： 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.

摘要： 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.
