英文摘要GdBaCo2O5+delta (GBCO)/poly (vinyl pyrrolidone) (PVP) composite nanofibers were prepared by electrospinning. Structural and morphological evolution of the GBCO/PVP fibers under calcinations at various temperatures was studied. Using 600 degrees C pre-calcined GBCO/PVP composite nanofibers, pure phase GBCO cathode with homogeneous network structure was easily fabricated on Ce0.9Gd0.1O1.95 (GDC) electrolyte. The as-prepared GBCO cathode was characterized by electrochemical impedance spectra (EIS) measurements based on a GBCO/GDC/GBCO symmetric cell. Its electrochemical performance was compared with the cathode prepared with the GBCO powders synthesized with sol-gel method. The GBCO cathode fabricated using GBCO/PVP composite fibers had area specific resistances (ASRs) of 0.53 Omega cm(2) at 600 degrees C, 0.22 Omega cm(2) at 650 degrees C, 0.10 Omega cm(2) at 700 degrees C and 0.043 Omega cm(2) at 750 degrees C respectively, which are lower than ASR results of the GBCO cathode prepared with powders. The results have demonstrated that the GBCO cathode fabricated using electrospun composite nanofibers has significantly enhanced electrochemical activities for oxygen reduction reaction, and it can serve as a promising cathode material for intermediate- temperature solid oxide fuel cell.
