N2 - For developing SOFC technology, multiphysics numerical tools are widely employed; reliability of numerical tools is hence quite important. Although the conventional current/voltage curve is considered as the basic validation method, it cannot itself assure the reliability of a mutliphysics SOFC model. Temperature-validation is herein proposed as a supplementary validation method for particularly ensuring the accuracy of the energy balance in the numerical tools. In this study, feasibility of the temperaturevalidation is investigated on a 2-dimensional microtubular-SOFC model. The characteristic properties of the SOFC were longitudinally computed by the model as well as they were in situ measured by the segmentation method along the cell. By comparing the numerical and experimental data, reliability of the validation methods are evaluated, i.e., improvement by the temperature validation is shown. Furthermore, the role of the temperature validation on the reliability of the computation was explained via elaborating the related voltage-losses.
