A novel high efficiency solid oxide fuel cell (SOFC) is proposed. The new SOFC comprises a cascade system in a unit, normal flow cells and internal reverse-flow cells. The cell is expected to afford higher energy efficiency through higher fuel utilization. Numerical analysis showed the temperature and current distribution profiles for the new SOFC and conventional type SOFC. By adopting an outside turn-round flow system, a lower heat value (LHV) of 60% was obtained, which is about 10% points higher than that of normal flow cells. Of the two types of internal reverse flow SOFC investigated, the outside turn-round was found to be preferable to the inside turn-round type in terms of temperature and current distribution.
