In this study, the chemical and thermal stabilities of eleven B2O3-free SiO2–Al2O3–SrO–La2O3–ZnO–TiO2 glasses were investigated, and the adhesion and sealing properties of the glasses with respect to Gd0.2Ce0.8O2−δ (GDC) electrolyte and SUS 430 stainless steel (SUS430) were evaluated for use in intermediate temperature solid oxide fuel cells (ITSOFCs).
