The performance of solid oxide fuel cell (SOFC) as a clean and efficient energy conversion device is often restricted due to the oxygen reduction reaction at cathode. As a potential cathode electrocatalyst, cobalt based double perovskite oxide, namely PrBaCo2O5+δ, has a high oxygen surface exchange coefficient and a great bulk diffusion coefficient. However, the physical and chemical properties (i.e., thermal expansion behavior) should be optimized to improve the electrochemical activity and durability as applying PrBaCo2O5+δ into SOFC. Therefore, recent work is devoted to modifying PrBaCo2O5+δ by element doping. This review summarized various element doping approaches, i.e., doping to the Pr site, Ba site, Co site, and O site. In addition, the doping effect on the PrBaCo2O5+δ properties (i.e., phase structure, oxygen nonstoichiometry δ, electronic conductivity, oxygen transport properties and electrochemical performances) was also discussed.
