Abstract
A novel cobalt-free perovskite oxide La0.6Sr0.4Fe0.9Mo0.1O3−δ (LSFM10) was prepared by a citric acid-nitrate process and investigated as a cathode material for intermediate-temperature solid oxide fuel cells (IT-SOFCs). It was discovered that the doping with Mo for Fe-site distinctly improved the electrical conductivity of the La0.6Sr0.4FeO3−δ sample. The maximum conductivity of LSFM10 reached 159Scm−1 at 300–800°C in air. A single cell with the LSFM10 cathode and the proton-conducting BaZr0.1Ce0.7Y0.2O3−δ (BZCY) electrolyte membrane (~35μm thickness) supported by a NiO–BZCY composite anode was fabricated and tested at 500–700°C with H2 as fuel and air as oxidant. The peak power density of the cell reached 496mWcm−2 and the interfacial polarization resistance was 0.15Ωcm2 at 700°C. The experimental results indicated that La0.6Sr0.4Fe0.9Mo0.1O3−δ is a suitable cathode material for the proton-conducting IT-SOFCs.
