Abstract

See full text

A crystallizable glass composition containing, in % by mole in glass component composition, 40 to 70% SiO2, 5 to 35% MgO, 5 to 35% BaO, 5 to 35% ZnO, 0 to 20% CaO, 0 to 20% SrO, 0 to 5% B2O3, 0 to 2% Al2O3, and 0 to 30% La2O3+Y2O3+Gd2O3+Nb2O5+Ta2O5. Provided is a crystallizable glass composition which has fluidity suitable for bonding, has a high coefficient of thermal expansion after undergoing thermal treatment, is less likely to degrade the power generation property of the fuel cell owing to evaporation of glass components even when exposed to high temperatures for a long period, and has excellent thermal resistance after bonding.
