Triple ionic-electronic conductors have received much attention as electrode materials. In this work, the bulk characteristics of oxygen diffusion and surface exchange were determined for the triple-conducting BaCo<sub>0.4</sub>Fe<sub>0.4</sub>Zr<sub>0.2-X</sub>Y<sub>X</sub>O<sub>3-δ</sub> suite of samples. Y substitution increased the overall size of the lattice due to dopant ionic radius and the concomitant formation of oxygen vacancies. Oxygen permeation measurements exhibited a three-fold de ...[more]
