LaFeO{sub 3}-based perovskites are of interest as cathode material for the development of advanced solid oxide fuel cells operating at temperatures significantly lower than 900 C. The compatibility of the selected materials is necessary to guarantee long-term operation of a solid oxide fuel cell. Systematic investigations on the reactivity between the solid electrolyte yttria-stabilized zirconia (ZrO{sub 2} + 8 mole percent Y{sub 2}O{sub 3}) and the perovskites (La{sub 0.6}Ca{sub 0.4}){sub x}Fe{sub 0.8}M{sub 0.2}O{sub 3} (x = 1, 0.9; M = Cr, Mn, Co, Ni) were carried out. The results obtained are discussed.
