      abstract     = {This work focuses on the deposition of thin-film
                      electrolytes. Sol–Gel Spin-coating technique has been used
                      to create thin films and subsequent characterization of the
                      different sub-surfaces has been undertaken. The substrates
                      are composed of ferritic oxide strengthened Fe–Cr alloy
                      (ITM). A common challenge in coating these supports is their
                      high roughness and porosity in comparison with
                      state-of-the-art ceramic substrates. Here, the nickel and
                      $8 mol.\%$ yttria-stabilized zirconia (8YSZ) based anode
                      is made of graded layers, which reduces the roughness and
                      porosity of the metal support. The quality of the thin
                      spin-coated electrolyte-layers depends on the microstructure
                      of the sub-surface. Influencial variables are the surface
                      roughness, the pore size and its depth. To understand the
                      dependencies between these variables and the coating
                      properties, analyses with various optical measurement
                      methods have been carried out prior to coating. Standard
                      roughness detection using optical profilometry and confocal
                      laser scanning microscopy were compared for surface
                      characterization. The Sobel edge detection method was used
                      to analyze images and was able to clearly reveal defects.
                      The fabricated electrolytes have a thickness ∼0.5 μm
                      with leak rates of 1 – 10×10–4
                      (hPa dm3 s–1 cm–2) against air of metallic
                      supported cells with a reduced anode, which are comparable
                      to those of anode-supported cells.},
