Abstract  The dimensions and the materials type limit the performance of fuel cell. The increase of the temperature in electrodes and electrolyte of the cell, is due to the over potential of activation (transfer of load), the over potential Ohmic (resistance of polarization), the over potential of reaction (heat released by the chemical reaction) and the over potential of diffusion. In this paper, we studied the thermo-electrical performance of an intermediate temperature solid oxide fuel cell (IT-SOFC) with electrode supported. The aim of this work is to study this increasing temperature of a single cell of an IT-SOFC under the influence of the following parameters: heat sources, functioning temperature and voltages of the cell, geometric configuration and materials type. The equation of energy in one dimension is numerically resolved by using the method of finite volumes. A computing program (FORTRAN) is developed locally for this purpose in order to obtain fields of temperature in every element of the cell.
