Abstract
A Gas turbine (GT) and solid oxide fuel cell (SOFC) hybrid system is expected to achieve a high efficiency over 60% LHV. However, in order to operate the system at such a high efficiency and an increased power density, it is important to keep the whole SOFC temperature as usiform as possible. Cathodic air recirculation is one of the most effective methods to improve the cell temperature distribution. In the present study, numerical simulation of GT-SOFC hybrid system with air recirculation is carried out. The ejector and blower systems are compared, and the effects of recirculation ratio on the overall system performance are evaluated. Furthermore, the part load performance of the ejector system is investigated.
