Three-dimensional modeling of transport phenomena in a planar anode-supported solid oxide fuel cell
In this article three dimensional modeling of a planar solid oxide fuel cell (SOFC) was investigated. The main objective was to attain the optimized cell operation. SOFC operation simulation involves a large number of parameters, complicated equations, (mostly partial differential equations), and a sophisticated simulation technique; hence, a finite element method (FEM) multiphysics approach ...
متن کاملAnode-supported thin-film fuel cells operated in a single chamber configuration 2T-I-12
The performance characteristics of anode-supported, thin-film, single chamber fuel cells (SCFCs) have been investigated. Cells, in which Ni+Sm0.15Ce0.85O2 (Samaria doped ceria, SDC) served as the anode and SDC as the electrolyte, were fabricated by dry pressing. High quality, bilayer structures with electrolyte thicknesses as small as 10 Am were prepared with excellent reproducibility. The cath...
متن کاملEvaluation of solid oxide fuel cell anode based on active triple phase boundary length and tortuosity
An efficient procedure is presented for the evaluation of solid oxide fuel cell (SOFC) anode microstructure triple phase boundary length (TPBL). Triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of SOFC because all electrochemical reactions of anode take place in its vicinity. Therefore, evaluation of TP...
متن کاملImportance of Anode Microstructure in Modeling Solid Oxide Fuel Cells
A one-dimensional button-cell model is developed and applied to explore the influence of anode microstructure on solid oxide fuel cell (SOFC) performance. The model couples porous-media gas transport and elementary electrochemical kinetics within a porous Ni-YSZ cermet anode, a dense YSZ electrolyte membrane and a composite LSM-YSZ cathode. In all cases the fuel is humidified H2 and air is the ...
