Abstract [en]

The Ba0.5Sr0.5Co0.2Fe0.8O3 (BSCF) cathode material was synthesized and evaluated for cathode in low temperature solid oxide fuel cells (LTSOFCs). Using Ni as anode, Sm0.2Ce0.8O2(SDC)-carbonate composites as electrolyte and the BSCF as cathode to construct the fuel cell (LTSOFC), maximum power output of 860 mW/cm(2) has been achieved at 500 degrees C. The LTSOFC at a large area, 14 cm(2), has delivered 5 W corresponding to a power density of 358 mW/cm(2) at 510 degrees C. These results have been the first recorded for the best performance of SOFCs at low temperatures.
