Abstract

Information on the across-plane conductivity of films of solid-oxide electrolytes SrZr0.95Y0.05O3–δ and CaZr0.9Y0.1O3–δ deposited on ion-conducting supports is acquired by the impedance method. It is shown that the support/film interface and the intergrain boundaries considerably affect the across-plane charge transfer in the film. The effect of the crystallographic orientation of the YSZ support on the microstructure and conductivity of the CaZr0.9Y0.1O3–δ electrolyte film is demonstrated.
