Master Thesis, Department of Mechanical Engineering / A comprehensive analytical model of an indirect internal reforming type tubular Solid Oxide Fuel Cell (IIR-T-SOFC) has been developed. Two-dimensional axisymmetric multicomponent gas flow fields and quasi-three-dimensional electric potential/current fields in the tubular cell are simultaneously treated in the model with consideration of the involved phenomena such as internal reforming, electrochemical reactions and radiative heat transfer. By using this model, the characteristics of the operating state of an IIR-T-SOFC were numerically examined. As a result, it was shown how the thermal field and power generation characteristics of the cell were affected by the gas inlet temperature, air flow rate, steam-methane ratio, reforming catalyst distribution and thickness of the electrodes. In particular, the optimized catalyst distribution greatly reduced both the maximum temperature and temperature gradients of the cell with little negative impact on the power generation performance of the cell. / 京都大学 / 0048 / 修士 / 修士(工学) / Kyoto University / TFtmp
