LaFeO{sub 3} based perovskites are of interest as cathode material for the development of advanced SOFCs operating at temperatures significantly lower than 900 C. The compatibility of the selected materials is a necessary demand in order to guarantee long term operation of a SOFC. Systematic investigations on the reactivity between the solid electrolyte YSZ (ZrO{sub 2} + 8 mol % 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.
