Temperature gradients in microelectrode measurements: Relevance and solutions for studies of SOFC electrode materials
a r t i c l e i n f o Microelectrodes on solid electrolytes, contacted by current-collecting tips, have become increasingly important for analyzing electrochemical properties of electrode materials in solid state ionics. Samples are usually asymmetrically heated from the bottom side. It is shown experimentally, e.g. by thermovoltage measurements, impedance spectroscopy and infrared camera pictu...
متن کاملInfluence of Electrode Design and Contacting Layers on Performance of Electrolyte Supported SOFC/SOEC Single Cells
The solid oxide cell is a basis for highly efficient and reversible electrochemical energy conversion. A single cell based on a planar electrolyte substrate as support (ESC) is often utilized for SOFC/SOEC stack manufacturing and fulfills necessary requirements for application in small, medium and large scale fuel cell and electrolysis systems. Thickness of the electrolyte substrate, and its io...
متن کاملSpatiotemporal simulation of nickel oxide and carbon phases formation in solid oxide fuel cells (SOFC)
The formation of secondary phases in the porous electrodes is a severe mechanism affecting the lifetime of solid oxide fuel cells (SOFC). It can occur via various chemical mechanisms and it has a significant influence on cell performance due to pore clogging and deactivation of active surfaces and triple-phase boundary (TPB). We present a modeling and simulation study of nickel oxide formation ...
متن کاملorigins of armenia’s foreign policy and its foreign policy towards iran
foreign policy takes root from complicated matters. however, this issue may be more truth about armenia. although the new government of armenia is less than 20 years, people of this territory are the first ones who officially accepted christianity. in very past times, these people were a part of great emperors like iran, rome, and byzantium.armenia is regarded as a nation with a privileged hist...
15 صفحه اولApplication of surface enhanced Raman spectroscopy to the study of SOFC electrode surfaces.
SERS provided by sputtered silver was employed to detect trace amounts of chemical species on SOFC electrodes. Considerable enhancement of Raman signal and lowered detection threshold were shown for coked nickel surfaces, CeO(2) coatings, and cathode materials (LSM and LSCF), suggesting a viable approach to probing electrode degradation and surface catalytic mechanism.
