Dopant Implications in a Lanthanide Perovskite for Symmetrical Solid Oxide Fuel Cell Electrodes

Abstract

Performance, structural and resistive effects of two lanthanide perovskites, respectively doped with Barium and Calcium elements, were studied. This analysis enabled the identification of the individual component performance limiting factors as well as the formulation of a mathematical expression to explain the results. The model establishes a hypothesis to quantify the influence of the intrinsic conductivity (under reducing conditions) in the respective cell peak power densities of the materials assembled as anodes.
