Fabrication and characterization of Sm0.2Ce0.8O2−δ-Sm0.5Sr0.5CoO3−δ composite cathode for anode supported solid oxide fuel cell

▶ We present the original results of the development of an anode supported fuel cell with structure of Ni-YSZ (Anode)// YSZ (Electrolyte)// SDC (Function layer)//SSC-SDC (Cathode) and active area of 14 cm2. ▶ Characterization, compatibility, devices of the functional layer and management of material composition are investigated at the temperature range of 700-800  °C. ▶ This provides a useful clew to judge the feasibility for practical development of an IT-SOFC using SSC-SDC as the composite cathode materials. ▶ A noticeable performance identifies the superiority of this cell.
