1. Cr Vaporization and Oxide Scale Growth on Interconnects in Solid Oxide Fuel Cells
Abstract : The vaporization of Cr(VI) species and the greater electrical resistance caused by a growing oxide scale are probably the two most detrimental degradation mechanisms associated with the use of Cr2O3-forming alloys as the interconnect material in a Solid Oxide Fuel Cell (SOFC). High electrical efficiency, clean emissions and the possibility to utilize several types of fuels, such as hydrogen, alcohols and hydrocarbons are some of the great advantages of SOFC technology.

2. Improved Oxidation Resistance and Reduced Cr Vaporization from Thin-Film Coated Solid Oxide Fuel Cell Interconnects
Abstract : High electrical efficiency, clean emissions, and the possibility to operate on a great variety of fuels, such as hydrogen, alcohols and hydrocarbons are some advantages of Solid Oxide Fuel Cell (SOFC) technology. Too short lifetimes and high production costs have, however, limited the commercialization of this technology. READ MORE

3. Abatement of Chromium Emissions from Steelmaking Slags - Cr Stabilization by Phase Separation
Abstract : Chromium is an important alloying element in stainless steel but also environmentally harmful element. A number of mineralogical phases present in the slag matrix can contain chromium and lead to chromium leaching. READ MORE

4. The influence of SO2 on the high temperature corrosion of Fe and Fe-Cr alloys
Abstract : Sulfur dioxide is an important pollutant in combustion gases and plays a major role in the high temperature corrosion of many metals and alloys. This work investigates the influence of small amounts of SO2 on the high temperature corrosion of iron, chromium and several Fe-Cr alloys. READ MORE

5. 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
