Abstract

Solid oxide fuel cells (SOFCs) are composed of ceramic components, and the mechanical reliability of cells is a serious subject in the development of SOFCs. In particular, the durability of the cell components against stresses during practical operations is an important problem. To evaluate the mechanical reliability of SOFCs, the magnitude of the stresses in cell components and the strength of the components against the stresses must be considered precisely. In this article, mechanical stresses in cells and cell stacks are evaluated experimentally and numerically.
