Abstract: Composite doped ITSOFC(Intermediate Temperature Solid Oxide Fuel Cell ) cathode material of La0.6Sr0.4-xCaxCo1-yNiyO3-δ（LSCCN）was synthesized through solid-phase reaction.The crystal structure and forming process of LSCCN powder were investigated with XRD.The experimental results showed that Ca2+ could not be well mixed into the LaCoO3 lattice when x was 0.4.The crystal structure of the material was stable when the metal molar percentage of Ni was less than 5%, but it lost the single perovskite phase structure and presented the square K2NiF4 phase of LaSrCoO4 when the content of Ni increased.The SOFC(Solid Oxide Fuel Cell) cathode wafers could be made by mixing a specific amount of amylum and ethylic cellulose with LSCCN cathode powder.The electrical conductivity of the samples was measured by using the four-probe DC method from 100℃ to 800℃ in atmosphere.The electrical conductivity of the cathode wafers with perovskite structure was higher than 105 S·m-1, in which the electrical conductivity of the La0.6Sr0.2Ca0.2Co0.9Ni0.1O3-δ samples could reach 57701 S·m-1 when heated up to 800℃.The sample single crystal lattice structure changed significantly and its electrical conductivity decreased considerably when the molar percentage of Ca2+ or Ni2+ increased.
