Atomic Layer Deposition of Mixed Conducting Cathodes for Solid Oxide Fuel Cells, Fabrication and Characterization of Lead Sulfide Thin Films by Atomic Layer Deposition". Optimal process conditions were identified in order to avoid any unwanted change in material properties, such as crystallinity and scaffold strength, that have a direct impact on the degradation speed and physical integrity of the constructed scaffolds. This report presents a demonstration and characterization of a nanotubular array of solid oxide fuel cells (SOFCs) made of one-end-closed hollow tube Ni/yttria-stabilized zirconia/Pt membrane electrode assemblies (MEAs).
