The development of efficient, stable and inexpensive electrode materials is a key to the further commercialization of solid oxide fuel cells (SOFC). This should solve some problems of anode carbon deposition, sulfur toxicity and poor low-temperature performance of cathode oxygen reduction reaction (ORR). Recent studies indicate that some reducible transition metal element dopants could in situ exsolved from perovskite lattice in reducing atmosphere, and pinning on the surface to form a "nanometal/perovskite" composite structure. The material prepared by this method has some advantages of high performance, strong carbon deposition resistance, good stability, and good regeneration. This review represented recent work on the construction of nano-(in situ exsolved metal particles) micron-(perovskite oxide parent) heterostructure (collectively referred to as nano-and micron-isomerisms) perovskite oxide composite electrode with a nanofiber morphology from the perovskite parent selection, A/B site doping, defect manipulation, topological ion exchange, and phase transition trigger. The affecting factors on the SOFC performance and stability were also summarized. In addition, the advantages, disadvantages, and prospects of the nano-and micron-isomer materials were also discussed.
