Development of cathodes for methanol and ethanol fuelled low temperature (300-600 degrees C) solid oxide fuel cells
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
We have made extensive efforts to develop various compatible cathode materials for the ceria-carbonate composite (CCC) electrolytes to be used in direct alcohol fuelled solid oxide fuel cells (DLFC). The following cathode ...
Numerical and experimental investigation of two-phase flow in an electrochemical cell
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
in this study, a two-phase mathematical model is adapted to study void fraction distribution, flow field and characteristics of electrolysis process. The model involves transport equations for both liquid and gaseous phases. ...
Micro level two dimensional stress and thermal analysis anode/electrolyte interface of a solid oxide fuel cell
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
The delamination and degradation of solid oxide fuel cells (SOFCs) electrode/electrolyte interface is estimated by calculating the stresses generated within the different layers of the cell. The stresses developed in a ...
Measurement of the temperature distribution in a large solid oxide fuel cell short stack
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
During the operation of solid oxide fuel cells (SOFCs), nonhomogeneous electrochemical reactions in both electrodes and boundary conditions may lead to a temperature gradient in the cell which may result in the development ...
Effect of binder burnout on the sealing performance of glass ceramics for solid oxide fuel cells
(ELSEVIER SCIENCE BV, 2013)
The glass ceramics composite sealants are among few materials suitable for the solid oxide fuel cells (SOFC) due to their high operating temperatures (600 degrees C-850 degrees C). The glass ceramics chemically bond to ...
Anode-supported solid oxide fuel cells with ion conductor infiltration
(WILEY-BLACKWELL, 2011)
Nano ion conductor infiltration to anode andcathode side of solid oxide fuel cell (SOFC) significantly improves the performance of an SOFC. The effects of processing parameters such as molar concentration, sintering ...
Application of a coating mixture for solid oxide fuel cell interconnects
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Due to high operating temperature (800-1000 degrees C) of SOFC's, limited number of alloys can be employed for the purpose of current collection. The electrical conductivity of these alloys usually decreases during the ...
A review on micro-level modeling of solid oxide fuel cells
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)
Solid oxide fuel cells (SOFCs) are ceramic based electrochemical devices operating at high temperatures and generates electricity and useful heat energy utilizing various fuels at a high efficiency. The main structure of ...
Electrochemical behaviour and sulfur tolerance of VxMo(1-x)Oy as solid oxide fuel cell anode
(ELSEVIER SCI LTD, 2013)
Vanadium molybdenum oxide system (VxMo(1-x)Oy for x <= 0.13) is synthesized through reducing acidified vanadate and molybdate solution at 60 degrees C by passing hydrogen sulfide gas through the solution. The electrochemical ...
Three dimensional stress analysis of solid oxide fuel cell anode micro structure
(PERGAMON-ELSEVIER SCIENCE LTD, 2014)
One of the most common problems in solid oxide fuel cells (SOFCs) is the delamination and thus the degradation of electrode/electrolyte interface which occurs in the consequences of the stresses generated within the different ...
