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 ...

Operation of Thin-Film Electrolyte Metal-Supported Solid Oxide Fuel Cells in Lightweight and Stationary Stacks: Material and Microstructural Aspects

In this study we report on the development and operational data of a metal-supported solid oxide fuel cell with a thin film electrolyte under varying conditions. The metal-ceramic structure was developed for a mobile auxiliary power unit and offers power densities of 1 W/cm² at 800 °C, as well as robustness under mechanical, thermal and chemical stresses. A dense and thin yttria-doped zirconia ...

Electrochemical Oxidation Kinetics of Hydrogen and Higher Hydrocarbon Fuels on Solid Oxide Fuel Cells

Title of Document: ELECTROCHEMICAL OXIDATION KINETICS OF HYDROGEN AND HIGHER HYDROCARBON FUELS ON SOLID OXIDE FUEL CELLS. Oktay Demircan, Ph.D., 2007 Dissertation Directed By: Professor Bryan W. Eichhorn, Department of Chemistry and Biochemistry Solid oxide fuel cells (SOFCs) are promising electrochemical energy converting devices due to their ability to use not only hydrogen but also hydrocarb...

Modeling of Solid Oxide Fuel Cells

A comprehensive membrane-electrode assembly (MEA) model of Solid Oxide Fuel Cell (SOFC)s is developed to investigate the effect of various design and operating conditions on the cell performance and to examine the underlying mechanisms that govern their performance. We review and compare the current modeling methodologies, and develop an one-dimensional MEA model based on a comprehensive approa...
