Abstract
At present, the insufficient thermo-mechanical stability of sealing glass presents a challenge for solid oxide fuel cells (SOFCs). In this work, we report for the first time that a rigid-resilient transition occurs in a calcium borosilicate sealing glass upon heating at 700â¯Â°C for different durations. The elastic modulus increases from 28.1-40.0â¯GPa for 24â¯h to 92.3-105.1â¯GPa for 100â¯h, while the corresponding hardness increases from 2.5-3.1â¯GPa to 8.1-9.2â¯GPa. In addition, a possible mechanism for the rigid-resilient transition has been proposed. The reported results provide a new approach to solve the sealing problem of SOFCs.
