A titanium-supported Solid Oxide Fuel Cell (SOFC) is a promising alternative to a steel-supported SOFC, being an innovative energy supply for novel unmanned aerial, marine, and space vehicles, and soldier ammunition. The studies performed by the Directors/Co-Directors from Ukraine, Turkey, Azerbaidjan, and the Czech Republic confirm that Ti-MAX phases and Ti-Si-based nanocomposites can be used as successful light-weight competitors to high-temperature iron-based materials in SOFCs. The major goal of the project is to develop a novel 600 °C SOFC system based on thin-film electrolyte/electrodes deposited by the Electron Beam Physical Vapor Deposition (EB-PVD) onto heat-resistant titanium composite support, interconnect, and casing.
