Evaluation of La0.6Sr0.4Co0.2Fe0.8O3-δ as a potential cathode for proton-conducting solid oxide fuel cell

The application of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) as a potential cathode working on a BaCe0.54Zr0.36Y0.1O2.95 (BCZY) electrolyte for proton conducting solid oxide fuel cell was investigated. LSCF nanoceramic powders were synthesized by an activated carbon-assisted sol-gel process using metal nitr...
