Solid oxide fuel cell (SOFC) has been attractive as a way to solve global energy and environmental problems. As the SOFC has layered structure consisting of different materials, there is significant residual and thermal stresses produced during sintering process and operating, which could affect the power performance of the SOFC. hi the present study, the effect of the stress on the ionic conductivity of 8 mol% yttria-stabilized zirconia electrolyte has been investigated by molecular dynamic simulation, allowing for the direction of the crystal axis. The results show that there is an optimum stress state for the oxygen migration.
