The present invention relates to a strontium magnesium molybdenum oxide material having perovskite structure and the method for preparing the same. Citric acid is adopted as the chelating agent. By using sol-gel pyrolysis and replacing a portion of strontium in Sr2MgMoO6-δ by cerium and a portion of magnesium by copper, a material with a chemical formula of Sr2-xCexMg1-yCuyMoO6-δ is produced, where 0≦x<2, 0<y<1, and 0<δ<6. Thereby, the electrical conductivity of the material is improved. The perovskite-type cerium- and copper-replaced strontium magnesium molybdenum oxide significantly increases the electrical conductivity of the material and can be applied as the anode material for solid oxide fuel cell (SOFC).
A perovskite-type strontium magnesium molybdenum oxide material, having a chemical formula of Sr2-xCexMg1-yCuyMoO6-δ, where 0≦2, 0<y<1, and 0<δ<6.
