Symposium Energy Materials 2017: Materials in Clean Power
Presentation Title The Composite Materials with Semiconductor and Ionic Conductor for Novel Low Temperature Solid Oxide Fuel Cells
Author(s) Xunying Wang, Bin Zhu
On-Site Speaker (Planned) Xunying Wang
Abstract Scope Solid oxide fuel cells (SOFCs) are currently attracting increased interest for their high energy conversion, fuel flexibility and cleanness. Conventional SOFCs employ yttria-stabilized zirconia (YSZ) as the electrolyte. The YSZ based SOFCs usually work at high temperature about 1000C to ensure the high ionic conductivity of YSZ. However, the high temperature condition leads to various problems including the high cost of materials, hardness in sealing, long start-up and shut-down time, which limits the commercialization of the SOFCs. Develop new electrolyte materials is an effective approach to reduce the operation temperature. In recent years, we have discovered that the composite materials with semiconductor and ionic conductor possess much better ionic conductivity than the pure ionic conductor when they were used as the electrolyte for the low temperature SOFCs. In this presentation, major study results about the composite materials based SOFCs will be discussed.
