Abstract

Solid Oxide fuel cells (SOFC) are multi-material layered system with different thermo-mechanical properties. Due to their severe thermal loading, these layers have to meet high demands to preserve their mechanical integrity without initiation of fracture. The mechanical performance under loading caused by the manufacturing process or service conditions can be determined and assessed. Based on the mechanical properties of each layer and their interfaces, an energy criterion as a function of the crack length is used for predictions of possible crack extension in SOFC. A competition analysis between the crack deflection in the interfaces or penetration in the adjacent layer is presented.
