RPC electrode material study
Various aspects of RPC electrode material, such as surface smoothness, surface UV sensitivity and its resistance to HF attack, have been studied. Based on these studies we can direct our R&D effort to some of the most critical issues related to RPC performance and aging. & 2008 Elsevier B.V. All rights reserved.
متن کاملResistive Oxygen Sensor Using Ceria-Zirconia Sensor Material and Ceria-Yttria Temperature Compensating Material for Lean-Burn Engine
Temperature compensating materials were investigated for a resistive oxygen sensor using Ce(0.9)Zr(0.1)O(2) as a sensor material for lean-burn engines. The temperature dependence of a temperature compensating material should be the same as the sensor material; therefore, the Y concentration in CeO(2)-Y(2)O(3) was optimized. The resistance of Ce(0.5)Y(0.5)O(2-δ) was independent of the air-to-fue...

متن کاملImprovement of ionic conductivity of gadolinium doped ceria electrolyte with nano CuO sintering aid
Gadanium doped cerium oxide ceramic (GDC) is widely used as solid electrolytes in solid oxide fuel cells because of its high oxygen ion conductivity. In this study, the effect of addition of nano CuO as a sintering aid on the properties of GDC electrolyte were investigated. For this purpose, 0.2, 0.5, and 1% mole of nano Cuo was added to GDC ceramics, which was synthesized by the solid-state me...
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....
