AbstractSolid oxide fuel cells SOFCs are considered promising energy conversion devices thanksto their several potential benefits including low pollutant emissions high energyefficiency the possibility of using different kinds of fuels and the possibility to build CHPand hybrid systems However SOFC technology is still in embryonic infancy and manyproblems i e mechanical stress electrode sintering electrode and interconnect materialsand fabrication startup time must be solved in order to achieve the goal of a highlyefficient and clean energy system with at least the same reliability costs and lifetime of the traditional energy systems This challenge entails an increased research effort forindustry and research institutions in order to develop advanced numerical models andcomputer codes that can be used in both industrial and research environments for fuel cellsdesign and development This could yield a better understanding of the physical processesand help fuel cell designers to define more promising strategies In the present thesis numerical model of three dimensional SOFC is defined by consideringall the occurred phenomena in each component of the fuel cell using FLUENT software After validating model we concentrate to model two main cases an anode supported anelectrolyte supported SOFC in this thesis Then we studied the effect of variation of someoperating condition parameters such as operating temperature pressure and some otherparameters such as electrolyte thickness conductivity anode cathode porosity massfraction of hydrogen anode stoichiometric coefficient rate of mass flow inlet in bothanode s and cathode s channel anode thickness channel land area width and flowpattern on the polarization curve of these two main models
