The power generation characteristics of a tubular Solid Oxide Fuel Cell (SOFC) are studied based on a two-dimensional numerical simulation which considers momentum transfer, heat and mass transfer, electrochemical phenomena and equivalent electric circuit. Fuel, which is composed of hydrogen and steam, and air flows are assumed to be steady, laminar and axisymmetric. An activation overpotential model which considers temperature dependency is applied to calculate the local electric current density accurately. As a consequence of this study, details of the power generation characteristics of a cell are obtained. The activation overpotential decreases as the cell temperature increases, and it significantly affects the power generation characteristics.
