摘要：
Electrospinning is employed to fabricate Sm0.5Sr0.5CoO3-delta (SSC) nanofibers. One-dimensional nanofiber-based Sm0.5Sr0.5CoO3-delta-Gd0.2Ce0.8O1.9 (SSC-GDC) composite cathodes for solid oxide fuel cell (SOFC) are fabricated by infiltrating the GDC precursor solution into the SSC nanofibers scaffolds. Optimal polarization resistance of 0.038 Omega cm(2) at 650 degrees C is achieved when SSC: GDC mass ratio of 1:0.869 for infiltration is used. This value is 2.6 times smaller than the polarization resistance of nanoparticle-based SSC-GDC composite under identical testing conditions. Microstructural features of the SSC-GDC interface further support the cell performance results. The nanofiber-based SSC-GDC composite is proved to be an excellent candidate as cathode material for intermediate temperature SOFCs.
