Abstract
In this paper, we incorporate the surrogate model and substitution approach into electrochemo-mechanical analysis of plate shaped solid oxide fuel cell (SOFC). A local structure which is called in-plane unit structure (IPUS) is extracted from the plate shaped SOFC. The oxygen potentials of the IPUS as training data are obtained from the electrochemical potential analysis. A surrogate model using proper orthogonal decomposition is constructed from the oxygen potential of the IPUS obtained from the electrochemical potential analysis, and the distribution of oxygen potential in plate shaped SOFC is predicted by the surrogate model. The reduced expansion strain is calculated from the predicted oxygen potential. Then, a substitution approach using numerical plate testing is applied to analyze macro deformation considering mechanical behavior and thermal and reduced expansion.
