Microscopic Image-Based Finite Element Analysis of Porous Composite Cathode Microstructures

Vaidya, Sushrut; Kim, Jeong-Ho;

Full Article:

We reconstruct three-dimensional (3D) microstructures of porous ceramic composite cathodes of solid oxide fuel cells (SOFCs) using a series of two-dimensional (2D) images. We then discretize the reconstructed 3D models into 8-node brick elements, and analyze the models and performed stress and probability of failure analyses using a general-purpose commercial finite element (FE) software package. We numerically investigate the effects of volume fractions and temperature-dependent material properties on the thermo-mechanical stress behavior of cathode microstructures.
