abstract

Solid oxide fuel cells represent a potentially important application for ceramic materials. There are, however, some significant issues which can affect the reliability and durability of the cell. The generation of stresses and associated strains in fuel cells is an important concern that needs to be addressed in order to avoid mechanical failure of the cell. Few comprehensive studies have been published on the subject of stress analysis of planar and tubular SOFCs to-date, although various numerical methodologies have been used to obtaining the stress distribution in specific SOFC components over the last 10 years. The objective of this paper is to summarize the state-of-the art of solid oxide fuel cell stress analysis efforts so that the salient issues can be identified.
