Abstract: The need for an efficient electrochemical performance of new material has driven technological advancements in the area of solid oxide fuel cells (SOFCs). In fact, it is noticeable that the capacity of these SOFCs is usually a cathode – an active site for the electrochemical reduction of oxygen. For instance, Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) – a perovskite group of material has fascinating significant unique properties such as high conductivity, excellent in oxygen transport, as well as electrocatalytic activity. These outstanding features have propelled the BSCF to the fore one of the most popular cathode material in SOFCs. In addition, we postulated that if the cathode material is in the nanotubes form, it will also insistently provide additional versatility for such application due to its high surface area. In order to leverage the benefits of the cathode synergistically, we explore spin coating technique to achieve a precisely controlled thin film deposition, so that the cathode configuration can be engineered to control specific surface and bulk functionality. The goal of this innovation is integrating the nanostructured composites of BSCF cathode supported on electrolyte giving rise of efficiency up to one order of magnitude.
