Tortuosity factor τ of the solid phase is an important parameter for the accurate prediction of SOFC electrode conductivity. This work investigates the effect of computational domain on τ. The results show that a computational domain with cross section area of 15d∗15d (d: particle diameter) is necessary for the calculation of τ when 15% deviation is allowed. The result also validates that the anisotropic property of τ shown in the previous literatures is caused by the insufficient sample size. This study builds a framework for the further study of τ.
