This study details subtle compositional modifications (marginal A-site deficiencies and Cu B-site dopant additions) to a La0.8Sr0.2FeO3 (LSF-20) cathode material to enhance sintering below 1000 C. The interaction of the modified LSF-20 compounds with YSZ below 1000 C was also investigated. Initial single cell studies utilizing a (La0.8Sr0.2)0.98Fe0.98Cu0.02O3 cathode material on an anode supported YSZ cell have indicated power densities in the range 1.35-1.75 W/cm2 at 750 C and 0.7V.
