We fabricated ceria (CeO 2 ) nanofibers by applying a mixed solution of polyvinylpyrrolidone (PVP) and various concentrations of cerium nitrate hydrate (Ce(NO 3 ) 3 ) ranging from 15.0 to 26.0 wt % by the electrospinning process. Ceria nanofibers were obtained after calcining PVP/Ce(NO 3 ) 3 nanofiber composites at 873 and 1173 K. The SEM images indicated that the diameters of CeO 2 nanofibers calcined at 873 and 1173 K were smaller than those of nanofibers obtained at RT. As the amount of cerium increased, the diameter of CeO 2 nanofibers increased. XRD analysis revealed that the ceria nanofibers were in cubic form. TEM results revealed that the ceria nanofibers were formed by the interconnection of Ce oxide nanoparticles. The ceria nanofibers obtained at low concentrations of Ce (CeL) showed spotty ring patterns indicated that the ceria nanofibers were polycrystalline structure. And the ceria nanofibers obtained at high concentration of Ce (CeH) showed fcc (001) diffraction pattern. XPS study indicated that the oxidation of Ce shifted from Ce 3+ to Ce 4+ as the calcination temperature increased.

Microtubular solid oxide fuel cells were fabricated by the multi-dip coating of ceramic aqueous slurries on steel wire. This is a very convenient way to make small straight tubes without requiring special handling. Prepared NiO-GDC/GDC double layered tubes were separated by dissolving the pre-coated polystyrene layer in organic solvent, then were sintered at 1350°C. Then a cathode layer of LSCF-GDC was also formed on the double layered tubes with heat treatment at 1100°C. The prepared microtubular cell performs with a maximum power density of 0.34 W/cm 2 at 550°C. Microstructure observation of the tubes suggested the possibility of further improvement in cell quality.

“…Even though the planar design has higher power density, the tubular design has many advantages such as thermo-mechanical property and easy sealing. 1), 2) Decreasing the size of tubular SOFC to millimeter or sub-millimeter range increases the electrode area per unit volume, which leads to an increase in volumetric power density. It also improves the thermo-mechanical properties, thermo-cycling resistance and shortens start-up time.…”

Using multi-pass extrusion process, a t-ZrO2 support tube for small tubular solid oxide fuel cell (SOFC) was fabricated. After burning out of extrusion binder, lubricant and pore former, SOFC functional layers have been coated on the tube by slurry dip coating method. The cell configuration was composed of NiO-8YSZ, 8 mol% yttria stabilized zirconia (8YSZ), Gd0.2Ce0.8O1.9-x, (GDC) and La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) on the t-ZrO2 supported tube as anode, electrolyte, interlayer and cathode, respectively. Dense microstructure of electrolyte was achieved by co-sintering. Maximum power density of 349 mW/cm 2 was obtained at 850°C using pure H2 as fuel and stagnant air. The cell showed stability for a time period of 100 h at 850°C.
