Abstract

The cathode of solid oxide fuel cells (SOFC) is highly related with reduction of oxygen which is the critical factor for the cell performance. To increase power output, research for improving the cathode property is needed. And reducing the expensive, complicated process is essential for accepting SOFC as future energy source. In this study, Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3-δ (BSCF)/Gd_0.1Ce_0.9O_2-δ (GDC) core/shell nanofiber, which has advantages such as charge transfer and large reaction site, was investigated for cathode. One step electrospinning for synthesizing heterogeneous nanofiber was employed with solution containing BSCF particles and Gd(NO₃)₃, Ce(NO₃)₃ in dimethylfor-mamide(DMF). Porous GDC shell surrounds the surface of BSCF nanofiber which has diameter of 200nm after sintering at 600°C. Ideal structure for cathode which facilitates efficient paths for electron and ion was fabricated.
