Al2O3-SiO2-CaO-based sealing material was developed. The properties of high-temperature crystallization/softening, thermal behavior and interfacial bonding of the sealing material were observed in situ. The results show that the sealing material begins to soften at 850℃, spheroidizes at 900-1 000℃ and keeps amorphous at <1 100℃. In addition, the sealing material has a slight mass loss according to the thermal analysis, and it is bonded with the interconnect and the cell tightly, which is conducive to the application in solid oxide fuel cell (SOFC) stack. Two 5-cell solid oxide fuel cell (SOFC) stacks were assembled by the sealing material. The cycling and stability performance of SOFC stacks were tested. The results indicate that the open circuit voltage (OCV) of the stack reaches 6.0 V, showing an average OCV of 1.2 V for single cells. The stack 1 is operated under cycling conditions, showing no degradation before and after cycling. The stack 2 is operated under stability conditions, exhibiting no degradation for 300 h operation.
