  5. 5. Cr Vaporization and Oxide Scale Growth on Interconnects in Solid Oxide Fuel Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hannes Falk Windisch; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; Interconnect; Cr Vaporization; SOFC; Coatings;

    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.
