Abstract

In this study, we synthesized La_0.8Sr_0.2Co _0.8Fe_0.2O₃ (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.
