In this study, a homogenization method is employed to determine the values of effective elastic modulus for BaZrO3 which is a promising candidate material for electrolyte in solid oxide fuel cell (SOFC). Comparison between the homogenization
and the analysis data reveals that the difference becomes significant with increasing of porosity when upper 20%. The empire
mechanic behavior in a typical planar fuel cell is evaluated using finite element method (FEM). Large stress gradient occurs
in vicinity of the interface of the electrolyte and the cathode due to theirs mismatch of thermal expansion coefficient (TEC).
Moreover, local processing results reveal that microscopic stress concentration around pore near the interface of the electrolyte
and the cathode in the cell perhaps produces cracks which may lead to the fail of the electrolyte and the lower energy convention
efficiency. 相似文献
