Reactivity of Lanthanide Ferrite SOFC Cathodes with YSZ Electrolyte

Abstract

The reactivity of yttria-stabilized zirconia (YSZ) with compounds of the form Ln0.8Sr0.2FeO3 (Ln = Sm, Pr, Nd and a mixed lanthanide precursor) and La0.8M0.2FeO3 (M = Ba, Ca) was investigated, and compared to the comprehensively studied La0.8Sr0.2FeO3 (LSF-20) composition. With the exception of Ca, all variants showed either increased reactivity with YSZ (compared to the base LSF-20), or a lack of phase purity after calcination at 1200-1300?C.
