Electronic and Structural Properties of Oxides

In this study, an anode-supported hollow-fiber solid oxide fuel cell (SOFC) of diameter 1.7 mm has been successfully fabricated using the phase inversion and vacuum assisted coating techniques. The cell has a special structure consisting of a 12-μm-thick yttria-stabilized zirconia (YSZ) electrolyte film and a Ni-YSZ anode layer which has large finger-like pores on both sides of the hollow-fiber membrane. The hollow-fiber SOFC has an active electrode area of 0.63 cm2 and generates maximum power densities of 124, 287 and 377 mW cm−2 at 600, 700 and 800 °C, respectively, indicating that its use in applications requiring high power density is promising.
