CO MPUTATIONAL STUDY OF SOLID OXIDE FUEL CELLS USING THE COMSOL MULTIPHYSICS SOFTWARE

In this research, a mathematical model of solid oxide fuel cell in a steady state condition is presented to study the transport phenomena and the reactions which are carried out in it. The consider equations are mass, energy and momentum conservation, charge balance, as well as the electrochemical and fuel reaction kinetic equations. To improve the accuracy of the electrochemical analysis result, thermodynamical and physical parameters are consider dependent on temperature, voltage and cell power, and the geometry is modelled by five-layer model. The model result include theeffect of temperature on the output power of the cell at different voltage, the polarization of both cocurrent and counter-current flow, the cathode current density distribution for the ionic conductivity and the distribution of the mole fraction of the gases involved in the reaction
