Paper Title:
Electrochemical Properties of Perovskite Cathode for Solid Oxide Fuel Cell
  Abstract

Gd-doped ceria electrolyte (Ce0.8Gd0.2O1.9, GDC, 700 μm thick), 30 vol% Ni-GDC cermet anode and perovskite cathode La0.6Sr0.4CoO3 (LSC) or La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) were used to evaluate the electric power of the cell using 3 vol%-H2O containing H2 fuel at 873 and 1073 K. Terminal voltage, ohmic resistance and overpotential were analyzed during the operation of the cell. The maximum power density with LSC and LSCF cathode was 53 and 113 mW/cm2 at 1073 K, respectively. The ohmic resistance and overpotential at the cathode was smaller for LSCF than for LSC.
