【Abstract】 In order to obtain SOFC anode materials with excellent electrical properties, we improved the conductivity and catalytic activity of the materials by doping the pure SrTiO₃. In this paper, the research progress of A-doped, B-doped and（A, B） co-doped SrTiO₃ anode materials is reviewed. The effects of doping on SrTiO₃ anode materials were analyzed from different doping types, doping elements, doping concentration, atmospheric conditions, sintering temperature and defect types. The common doping elements in the Asite are La and Y. The common doping elements in the B site are Fe and Nb. The electrical properties of the material are improved by doping at the A or B site. The（A, B） co-doped SrTiO₃ can suppress the occurrence of a reaction between the anode and the solid electrolyte, and improve the stability of the material. In addition, the（A, B） co-doped SrTiO₃ with the A-site-deficient is beneficial to increase the ionic conductivity of the material and improve the electrical properties of the material.更多还原
