摘要：

LST28 nanofibers prepared by electrospinning can be sintered on ScSZ electrolyte at 1000 degrees C without formation of secondary phase. LST28 nanofibers with an electronic conduction pathway on ScSZ electrolyte provide an efficient anchoring scaffold for the infiltrated Gd0.2Ce0.8O1.9 (GDC). The microstructure morphology and elemental distributions of Gd0.2Ce0.8O1.9-La0.2Sr0.8TiO3 (GDC LST28) have been investigated in detail. GDC greatly improves the electrochemical performance of the fuel electrode. GDC LST28 (0.92:1) composite anode gives the low interfacial polarization resistances (R-p) of 0.95, 0.63, 0.38 and 0.27 Omega cm(2) at 800, 850, 900 and 950 degrees C, respectively. The adding of GDC has greater influence on reducing low frequency region resistance of the polarization resistance than high frequency region resistance. The fuel cell with the GDC LST28 composite anode has good thermal cycling stability. (C) 2014 Elsevier B.V. All rights reserved.
