چکیده انگلیسی
La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) based thin film cathodes were fabricated by spray pyrolysis and their performance was evaluated with area specific resistance (ASR). With a maximum processing temperature of 650 °C, these cathodes are suitable for application in micro-solid oxide fuel cells (μ-SOFC). The ∼ 500 nm thick cathodes showed performance similar to traditional thick film LSCF cathodes (10–100 μm). However, by using a new material composition Ba0.25La0.25Sr0.5Co0.8Fe0.2O3 − δ (BLSCF) or by modifying the microstructure, a significant improvement in performance was achieved. Reducing the grain size or introducing a thin dense cathode layer between the porous cathode and the electrolyte were beneficial modifications of the microstructure.
