Analysis of the tubular SOFC system using non-isothermal simulation

We have developed a non-isothermal simulation program incorporating inner reforming for a SOFC system using tubular cells. In this paper, the following points are considered, (i) including the radiation heat transfer, (ii) modeling shape of a half-sphere at the bottom of the cell, and (iii) applying the experimental results of electrodes performance of a tubular cell made by the electrochemical vapor deposition. This simulation reveals the details of the temperature and current distributions. From these results, we discuss the reliability of tubular SOFC systems.
