title: Study on nanocomposites based on carbonate@ceria.
abstract: Nanocomposites based on the ceria-carbonate composite have demonstrated as electrolytes in development of successful 300-600 degrees C fuel cell technology. In this paper, the nanocomposite electrolyte based on carbonate@SDC (SDC: samarium doped ceria) was directly synthesized from the co-precipitation method and characterized by XRD, SEM, TEM, BET, etc. It was proved that the carbonate@SDC was a two-phase material with average particle size about 14.5 nm (S(BET)) and crystalline size (D(XRD)) ranged from 12 to 14 nm. When the carbonate@SDC electrolyte was used to fabricate single SOFC, the cell shows remarkable performance with maximum power density 1000-1180 mw/cm2 at low temperature (300-550 degrees C).
