Abstract Scope In this study, four categories of glass compositions were explored for use in intermediate temperature solid oxide fuel cells (ITSOFCs), including glasses containing boron oxide and alkaline earth metal (AEM) oxide, glasses with boron oxide and free of AEM oxides, glasses with AEM oxides but boron oxide free, and glasses with boron oxide and AEM oxides free. The thermal stability, adhesion, and sealing properties of the glass systems with respect to SUS 430 stainless steel (SUS430) were examined. The glass transition points fell in the range of 632°C and 819°C. Glasses, containing AEM oxides, showed lower glass crystal temperatures (<785°C) and high thermal expansion coefficients (CTE; >11.6 ppm/°C) which are compatible to that of SUS430, while those glasses without AEM oxides have lower CTEs and, however, possessed good thermal stability at 700°C. It was observed that AEM oxides containing glasses indicates high leak rates, but good bonding strength with SUS430.
