6. Corrosion of Ferritic Stainless Steels Used in Solid Oxide Fuel Cells
Abstract : Solid oxide fuel cells (SOFC) are energy conversion systems with clean emissions (depending on the fuel used) and high electrical efficiencies, which could potentially replace conventional conversion systems such as combustion engines. However, other issues, such as high costs and limited lifetime, must be resolved before widespread commercialization of SOFCs can be achieved. READ MORE

9. Metallic materials in Solid Oxide Fuel Cells: Oxidation and chromium evaporation properties
Abstract : Solid oxide fuel cells (SOFCs) are high-temperature energy conversion devices which have great potential due to their high efficiency, low operating costs and flexibility in using conventional hydrocarbon based fuels. However, system cost, durability and performance stability in long-term operation are barriers to the widespread commercialization of SOFC technology. READ MORE

10. Tailoring of adsorptive properties of zeolites for biogas upgrading
Abstract : Biogas is a promising alternative fuel with low CO2 emissions and high market potential due to the abundance of organic biomass. Despite being a renewable form of energy, biogas consists of 40-45% CO2, which lowers its calorific value [1]. READ MORE
