  3. 22. Ceria-based nanocomposite electrolyte for low-temperature solid oxide fuel cells

    Författare :Ying Ma; Mamoun Muhammed; Peter Lund; KTH; []
    Nyckelord :;

    Sammanfattning : Solid oxide fuel cells (SOFCs) have attracted much attention because of their potential of providing an efficient, environmentally benign, and fuel-flexible power generation system for both small power units and for large scale power plants. However, conventional SOFCs with yttria-stabilized zirconia (YSZ) electrolyte require high operation temperature (800-1000°C), which presents material degradation problems, as well as other technological complications and economic obstacles.

  4. 23. Ceria-based Nanostructured Materials for Low-Temperature Solid Oxide Fuel Cells

    Författare :Ying Ma; Mamoun Muhammed; Bin Zhu; Randa Abdel-Karim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : As one of the most efficient and environmentally benign energy conversion devices, solid oxide fuel cells (SOFC) have attracted much attention in recent years. Conventional SOFC with yttria-stabilized zirconia as electrolyte require high operation temperature (800-1000 °C), which causes significant problems like material degradation, as well as other technological complications and economic barrier for wider applications.

  5. 24. Chemical-Looping Combustion with Liquid Fuel — Operation in a 300W Chemical-Looping Combustor

    Författare :Patrick Moldenhauer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oxygen carrier; kerosene; circulated fluidized bed CFB ; liquid fuel; CO2 capture; chemical-looping combustion CLC ;

    Sammanfattning : Chemical-looping combustion (CLC) is a promising technology for future energy production based on combustion of fossil fuel with inherent CO2 separation. In comparison to other carbon capture technologies there is no need for energy demanding gas separation using CLC in order to obtain pure CO2. LÄS MER
