Nanostructuring the electrodes of solid oxide cells via atomic layer deposition

In this chapter, recent progress in atomic layer deposition (ALD)-modification of nanostructured electrodes in SOCs is reviewed. The review starts with an introduction describing the need for nanostructured electrodes and why ALD can meet the need. The review then briefly presents the working principle and basic procedure of ALD process. The applications of ALD in SOCs are then reviewed in porous oxygen electrodes, barrier layer, electrolyte, and fuel electrodes. Last, the limitations of ALD technique in SOCs are candidly discussed.
