Abstract

Microstructure-property relations of solid oxide fuel cells are studied using ZrO2-In2O3 as a model electrolyte/electrode, and ZrO2(Y2O3)-La0.85Sr 0.15MnO3-Pt mesh as a model electrolyte/electrode/current collector. Electrochemical performance of the cells depends strongly on the microstructure of electrode as well as the geometry of the current collectors. A decrease in effective electrode area occurs both on the microscopic level with a coarse and inhomogeneous electrode microstructure and on the microscopic level with a wide contact spacing of the current collectors. Microstructure tailoring as well as the current collector geometry becomes important with decreasing operation temperalure of the fuel cells.
