Title: Nanoscale SOFC electrode architecture engineered using atomic layer deposition

Abstract

One embodiment includes forming surface-modifying phases on a surface of a functional electrode via atomic layer deposition and controlling the chemistry of constituent phases, the crystalline nature of the constituent phases and the thickness of the surface-modifying phase via the atomic layer deposition such that the thickness is between about 2 nm to about 200 nm. The surface-modifying phases enhances the performance of electrocatalytic activity of the functional electrode and the device.
