Interface Reaction Between LSMC and YSZ and Impedance Properties

ABSTRACT

Interface reaction between LSMC and YSZ is discussed with chemical composition of LSMC. The reac-tivity between LSMC and YSZ increased with increasing Co amount and A-site deficient perovskite is very effective on reducing reactivity. The (La0.8Sr0.2)xMn0.8Co0.2O3 (X=0.9-1) composition is not reactive with YSZ in experimental range. The electrode reaction reaction resistance increases due to reaction product.

Key words: LSMC, Interface reaction, Electrode reaction resistancef. A-site deficient perovskite
