Optimized Lanthanum Ferrite-Based Cathodes for Anode-Supported SOFCs

Abstract
Three cathode compositions and have been tested as solid oxide fuel cell (SOFC) cathodes at operating temperatures from 650 to 750°C. Sintering temperatures were established for each cathode composition to provide optimized cell performance. exhibited the highest power density at 750°C and 0.7 V), and indicated excellent performance stability over a 300 h period. © 2002 The Electrochemical Society.
