    Författare :Rakshith Nugehalli Sachitanand; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interconnect; Fuel Cell; Energy; SOFC; Steel; Corrosion;

    Sammanfattning : Solid Oxide Fuel Cells (SOFCs) are electrochemical energy conversion devices that have the potential to achieve high efficiencies while using a broad range of fuels. The advancement of the technology has however been hindered by a number of technical and economic barriers, one of which is the durability and cost of the bipolar plate or interconnect that connects individual cells in series to form a so-called ‘stack’.

    Sammanfattning : 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.
