This work summarizes results of design of planar thin-film solid oxide fuel cells(SOFC) and their performance characterization in the intermediate (600-800 ° C)temperature range. Thin (5-20 μm) layers of electrolyte (YSZ, ScCeSZ) were supportedon either cathodic (LSM) or anodic (NiO/YSZ, either bulk or supported on new type of compressed Ni-Al foam plates) substrates by using MO CVD or aerosol colloidaldeposition. Functionally graded cathode layers comprised of perovskites (La-Sr-Mn-O,La-Sr-Fe-Co-O, La-Sr-Fe-Ni-O, etc) and interlayers comprised of Gd-doped ceria (GDC)or nanocomposites of perovskites with electrolytes such as GDC, ScCeSZ were depositedon thin electrolyte layers. Porosity of Ni-Al foam substrates, composition andmicrostructure of cathode and anode layers (NiO/YSZ promoted with Ru/Ln-Sr-Mn-Cr-Onanocomposites), their depositing and sintering procedures (including application ofelectron beam or microwave radiation techniques for sintering) were optimized toprovide a good adhesion of layers, their high conductivity and efficient activation of O2and fuel (H2, CH4) molecules. For button-size cells power density up to 1190 mW/cm2(800°C) -350 mW/cm2 (600°C) was obtained using wet H2-air feeds. High and stableactivity of structured nanocomposite catalyst on Ni-Al foam substrate in CH4 steamreforming without heat and mass transfer limitations provides close power density usingCH4 +H2O feed with a small excess of steam without degradation for at least 100 h. SEM-EDX studies of cells after testing revealed neither cracks nor detachment of cathodelayers from electrolyte layers/formation of isolating pyrochlore-like layers providedfunctionally graded cathodes were properly optimized.
