One of the primary scientific aims within the solid oxide fuel cell (SPOFC) community is to lower the operating temperature of an SOFC system from about 800-1,000 °C to intermediate temperatures of about 600 °C [1]. The lower operating temperature decreases thermal stress in the materials and offers
The La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 (LSCF) nanoceramic powders were prepared by solegel process using nitrate based chemicals for SOFC applications since these powders are considered as more promising cathode materials for SOFC. The citric acid was used as a chelating agent and ethylene glycol as a
