Thermodynamic Stability of Gadolinia-Doped Ceria Thin Film Electrolytes for Micro-Solid Oxide Fuel Cells
Next-generation micro-solid oxide fuel cells for portable devices require nanocrystalline thin-film electrolytes in order to allow fuel cell fabrication on chips at a low operation temperature and with high power outputs. In this study, nanocrystalline gadolinia-doped ceria (Ce0.8Gd0.2O1.9!x) thin-film electrolytes are fabricated and their electrical conductivity and thermodynamic stability are...
متن کاملStudy of ceria-carbonate nanocomposite electrolytes for low-temperature solid oxide fuel cells.
Composite and nanocomposite samarium doped ceria-carbonates powders were prepared by solid-state reaction, citric acid-nitrate combustion and modified nanocomposite approaches and used as electrolytes for low temperature solid oxide fuel cells. X-ray Diffraction, Scanning Electron Microscope, low-temperature Nitrogen Adsorption/desorption Experiments, Electrochemical Impedance Spectroscopy and ...
متن کاملSolid-state graft copolymer electrolytes for lithium battery applications.
Battery safety has been a very important research area over the past decade. Commercially available lithium ion batteries employ low flash point (< 80 °C), flammable, and volatile organic electrolytes. These organic based electrolyte systems are viable at ambient temperatures, but require a cooling system to ensure that temperatures do not exceed 80 °C. These cooling systems tend to increase ba...
متن کاملEffect of Dopant on Improving Structural, Density and Functional Properties of Ceria Based SOFC Electrolyte
In the present work, Gadolinium Doped ceria (GDC) based solid electrolyte was successfully synthesized through wet chemical method to operate at intermediate temperature (500–700°C) for SOFCs. DSC study revealed the formation of GDC phase at 900°C during calcination. The crystal structure of GDC was identified as cubic fluorite phase and the crystallite size was found to be around 23 nm....
متن کاملResistance-change devices based on solid electrolytes
Scalable elements that can be switched between widely-separated non-volatile resistance states at very low power are desirable for applications in next generation memory and logic. One potential approach involves the use of solid electrolyte films. A mobile metal ion-containing electrolyte film sandwiched between an oxidizable metal layer and an inert electrode constitutes a device which revers...
