The delamination and degradation of solid oxide fuel cells (SOFCs) electrode is estimated by calculating the stresses generated within the different layers of the cell. The structural and mechanical properties of the cell materials (i.e. porosity, density, grain size, etc.) are usually assumed to be homogenous in the mathematical modeling of solid oxide fuel cells at macroscale. However, during the operating of these composite materials the real stresses on the multiphase porous layers might be very different than those at macro- scale. Therefore microlevel modeling is needed for an accurate estimation of the real stresses and the performance of SOFC. In this study, anode composite of SOFC were consisted to use Dream 3D package program. Three different phases distribution in anode composite layer are generated. The synthetic microstructure of anode composite layer will help to analyses the mechanical properties and performance of anode composite SOFC.
