   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

7. 10. Ionic Conducting Composite as Electrolyte forLow Temperature Solid Oxide Fuel Cells

   Författare :Xiaodi Wang; Mamoun Muhammed; Zhu Bin; Per H Alvfors; KTH; []
   Nyckelord :;

   Sammanfattning : Solid oxide fuel cells (SOFCs) are considered as one of the most promising powergeneration technologies due to their high energy conversion efficiency, fuel flexibilityand reduced pollution. The current SOFCs with yttria-stabilized zirconia (YSZ)electrolyte require high operation temperature (800-1000 °C), which not only hinderstheir broad commercialization due to associated high cost and technologicalcomplications.
