The importance of the simulation model thus showed by these results. As the electrochemical reaction rates are more effective at the inlet of the fuel cell so, the highest current density occurs As the demand of today''s requirement of energy production technology of SOFCs that it must have up to the higher extent of stability and reliability. Temperature profile distribution homogeneity is one of the accountable factors for the steady SOFCs operation for its long-lasting working. To investigate and to improve the performance of SOFCs cell the numerical analysis is carried out by developing the rectangular SOFC single cell numerical model. In this study of numerical investigation of humidified fuel injection through SOFC has investigated, where the performance of the cell has been improved by increasing humidity at the anode in counter and co-flow configuration. Also, the electrochemical performance of the model numerically investigated by varying the injecting fuel humidification. As for the consideration of electrolyte, ionic conductivity is a function of increasing temperature, so therefore at high temperature in SOFC increasing humidity linearly increase the conductivity. In this study, we assume that in co-flow the current density and temperature distribution is more influential at outermost parts of the cathode. Therefore the fuel flow configuration and as well as its humidification at high temperatures are one of the considerable factors to investigate performance effect and cell structure stability and reliability.
