Abstract

In this study, the analysis of a solid oxide fuel cell (SOFC) is conducted, starting at a high temperature under the assumption of a stress-free during cell sintering at that temperature level. The deformation during the temperature decrease after sintering is reflected not only in the initial shape of the cell at a low temperature, but also in the deformation behavior during operation. The time variation of the cell shape is clarified in terms of thermal, chemical, and creep strains. In these simulations, we use our previously developed analysis method for electrochemical and mechanical coupling phenomena by incorporating general-purpose finite element analysis software and its pre-/post-processing functions.
