Abstract
This document describes the nano-scaling effects of solid-state oxygen-ion conductors when the thickness of an ionic conductor membrane as well as size of the grains within the membrane are scaled down to less than 200 nm. By using such solid-state oxygen-ion conductor membranes as solid-state electrolytes, the performances of solid-state ionic devices like fuel cells, gas sensors and catalytic supporters, can be improved and operating temperature can be lowered.
