Abstract

We report systematic investigation of the surface properties of yttria-stabilized zirconia (YSZ) electrolytes with the control of the grain boundary (GB) density at the surface, and its effects on electrochemical activities. The \GB\ density of thin surface layers deposited on single crystal \YSZ\ substrates is controlled by changing the annealing temperature (750
