摘要：
Cathodes based on La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) and Sm0.5Sr0.5CoO3-delta (SSC) were fabricated by axial-injection plasma spraying using dry powder feedstock. Composite cathodes were produced with up to 40 wt.% Ce0.80Sm0.20O2-delta (SDC) in the feedstock. The processing parameters were varied to produce cathodes with different mechanical properties and microstructures. The best-performing LSCF-SDC cathode had a polarization resistance (Rp) of 0.101 Omega cm(2) at 750 degrees C, and the best-performing SSC cathode had a polarization resistance of 0.0056 Omega cm(2).
