Research and development of solid oxide fuel cells (SOFCs) have been mainly conducted from the aspect of electrochemistry and materials science to improve cell- and stack performances. Long-term reliability and durability are of great importance for the commercialization of SOFCs. Mechanical behaviors of ceramics components, including cell fracture, are necessary to be understood in order to ensure stability of SOFCs. For the multiscale simulation of the thermo-chemo-mechanical behavior, various related materials properties are indispensable. This paper reports the evaluation procedure for comprehensive analysis of chemically- and thermally induced mechanical behavior of SOFCs.
