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.

Nanoscale SOFC electrode architecture engineered using atomic layer deposition

Provided herein is a method for electrocatalyst infiltration of a porous substrate, of particular use for preparation of a cathode for a solid oxide fuel cell. The method generally comprises preparing an electrocatalyst infiltrate solution comprising an electrocatalyst, surfactant, chelating agent, and a solvent; pretreating a porous mixed ionic-electric conductive substrate; and applying the electrocatalyst infiltration solution to the porous mixed ionic-electric conductive substrate.
