Patent number: 10020515Abstract: 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-? by cerium and a portion of magnesium by copper, a material with a chemical formula of Sr2-xCexMg1-yCuyMoO6-? is produced, where 0?x<2, 0<y<1, and 0<?<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).Type: GrantFiled: July 14, 2016Date of Patent: July 10, 2018Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Tsui-Yun Chung, Chien-Kuo Liu, Jing-Kai Lin, Hui-Ping Tseng, Ruey-Yi Lee
