In this study, we synthesized La0.8Sr0.2Co 0.8Fe0.2O3 (LSCF) nanopowders by citric acid gel combustion method. The single perovskite phases LSCF nanopowders with an average particle size of less than 30 nm could be synthesized at 700 °C. In order to evaluate the use of the synthesized LSCF nanopowders as cathode material of solid oxide fuel cells (SOFCs), anode-supported SOFCs were fabricated from the synthesized LSCF nanopowders and tested in the conditions of 3%H2O-H2 for anode and oxygen for cathode. The anode-supported single cell with the LSCF cathode sintered at 700 °C showed the maximum power density of 771 mW/cm2 at 600 °C. This means that the synthesized LSCF nanopowders are suitable to be applied as cathode material for low-temperature SOFCs.
