Three cathode compositions (La0.8Sr0.2FeO3-d, La0.7Sr0.3Fe0.8Ni0.2O3-d and LaNi0.6Fe0.4O3-d) have been tested as SOFC cathodes at operating temperatures from 650?C to 750?C. Sintering temperatures were established for each cathode composition to provide optimized cell performance. La0.8Sr0.2FeO3-d exhibited the highest power density (> 900 mW/cm2 at 750?C and 0.7 V), and indicated excellent performance stability over a 300 hour period.
