dc.description.abstract | Sm0.2Ce0.8O1.9 (SDC)-embedded Sm0.5Sr0.5CoO3-delta (SSC) composite fibers were successfully fabricated by electrospinning using commercial SDC nanopowders and an SSC precursor gel containing polyvinyl alcohol (PVA) and hydrated metal nitrate. After calcination of the composite fibers at 800 degrees C, the fibers of 300 +/- 80 nm in diameter with a well-developed SSC cubic-perovskite structure and fluorite SDC were successfully obtained. An anode-supported single cell composed of NiO-Gd0.2Ce0.8O1.9 (GDC)/GDC/SSC-SDC fibers was fabricated, and its electrochemical performance was evaluated. The maximum power densities were 1250 and 360 mW/cm(2) at 700 and 550 degrees C, respectively, which we ascribe to the excellent properties of the SSC fibers with embedded SDC particles such as a highly porous and continuous structure promoting mass transport and a charge transfer reaction.
