摘要：
One-dimensional nanostructured CuCo2O4-Sm0.2Ce0.8O1.9(SDC) nanofibers are prepared by the electrospinning method and one step sintering as a cathode with low polarization resistance for intermediate temperature solid oxide fuel cells (IT-SOFC). The CuCo2O4-SDC nanofibers cathodes form a porous network structure and have large triple-phase boundaries. Correspondingly, the electrochemical performance of the CuCo2O4 -SDC nanofibers composite cathodes shows significantly improve, achieving the polarization resistance of 0.061 Omega cm(2) and the maximum power densities of 976 mW.cm(-2) at 750 degrees C. Thus, these results suggest that CuCo2O4-SDC nanofiber could be a highly active cathode material for IT-SOFCs. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
