A single planar solid oxide fuel cell model considering various temperature-dependent physical and chemical properties of the materials was proposed via multi-physics coupling based on the COMSOL multiphysics simulation platform. The effects of residual stress and nickel volume fraction in the anode material on the internal thermal stress of the fuel cell were investigated. The results show that the existence of residual stress increases the maximum tensile and compressive stresses of the electrolyte and the cathode electrode under working conditions, reduces the maximum tensile stress of the anode electrode and increases its maximum compressive stress. The increase in the volume fraction of nickel in the anode electrode firstly decreases and then increases the maximum tensile stress of each component of the SOFC. The optimal percentage of nickel volume fraction in the anode electrode is 40%-60%.
