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 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 ...
متن کاملAnode-Supported Solid Oxide Fuel Cells with Thin Film Electrolyte for Operation at Reduced Temperatures
In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), anodesupported cells incorporating thin film (~10 μm) electrolytes in conjunction with anode/electrolyte and cathode/electrolyte interlayers were studied. Anode supported button cells were prepared through a conventional approach and were analyzed via Scanning Electron Microscopy (SEM), Polarization, and Electrochem...
متن کاملHigh performance anode-supported tubular solid oxide fuel cells fabricated by a novel slurry-casting method
Tubular solid oxide fuel cells were fabricated and evaluated for their microstructure and electrochemical performance. The tubular substrate was prepared by casting NiO-Y2O3 stabilized ZrO2 (YSZ) slurry on the inner wall of a plastic mold (tube). The wall thickness and uniformity were controlled by slurry viscosity and rotation speed of the tube. The cells consisted of Ni-YSZ functional anode, ...
