1. Metallic materials in Solid Oxide Fuel Cells: Oxidation and chromium evaporation properties
Sammanfattning : 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. LÄS MER
2. The Breakdown of the Protective Oxide on 11% Chromium Steel The Influence of Water Vapour and Gaseous KCl
Sammanfattning : The first part of this thesis is focused on the influence of water vapour on the oxidation of X20 steel (CrMoV 11 1). Three parameters were investigated; pH... LÄS MER

4. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Sammanfattning : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. LÄS MER
5. Metallic materials for solid oxide fuel cells and electrolysers - Mitigating high temperature corrosion
Sammanfattning : Solid oxide cells (SOCs) are high-temperature energy conversion devices that have great potential due to their high efficiency, low operating costs, and flexibility. SOCs can produce electricity from a variety of fuels as solid oxide fuel cells (SOFCs), and they can convert electricity to fuels as solid oxide electrolyser cells (SOECs). LÄS MER
