Synthesize and Evaluation of Electrospun Perovskite (Ba_0.5Sr_0.5Co_0.2Fe_0.8O_{3- δ}) Nanofibers for Intermediate Temperature Solid- Oxide Fuel Cell

Abstract:

In recent years, one dimensional nanostructure, nanofibers with unique properties have been subjected of intense research due to potential properties in many applications. This study presents synthesize of Perovskite-type Ba0.5Sr0.5Co0.2Fe0.8O3−δ (BSCF) nanofibers using sol-gel via electrospinning as a cathode for intermediate temperature solid oxide fuel cell. BSCF nanofibers are prepared by treating electrospun polyvinyl Pyrrolidon/ Ba0.5Sr0.5Co0.8Fe0.2O3−δ composite fibers at high temperature in an air atmosphere. BSCF nanofibers were characterized by x-ray diffraction (XRD) to observe desired structure, scanning electron microscopy (SEM) to investigated the morphology of fibers, and Brunauer, Emmett and Teller (BET) for measuring the surface area. To the best of our knowledge, investigation on Ba0.5Sr0.5 Co0.2 Fe 0.8O3−δ nanofibers has not been reported up to now.
