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 SiO 2 , 3-35 wt% of B 2 O 3 , 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. |
