Abstract： The invention provides a coating-structure composite conducting ceramic material and a cathode contact layer, and their preparation method. The coating-structure composite conducting ceramic material can be used as a contact layer between a SOFC cathode and a connector and has a coating structure composed of a spinel structure and perovskite coated by the spinel structure. The coating-structure composite conducting ceramic material has low-temperature sintering activity of a spinel material. Through use of high-density and high-conductance perovskite particles, composite material electroconductibility can be effectively improved, and high perovskite electroconductibility and good sintering activity of reduced spinel powder are obtained. The coating-structure composite conducting ceramic material has a low cost and excellent performances, can replace an expensive precious metal as a contact layer material, can greatly reduce a SOFC preparation cost and has high application values.
