Abstract

In this paper, the detailed mathematical models are established for solid oxide fuel cell-humid air turbine (SOFC-HAT) combined cycle system, and the performances of the combined system are analyzed under variable conditions such as the fuel flow, pressure ratio and turbine initial temperature. At the typical working condition, the system efficiency reaches 73.86%, which is far more than that of the usual HAT cycle as well as the system combined with SOFC. The results disclosed in this paper can help to understand basic rules of the integrated system of SOFC and HAT so as to provide guidance for the design and operation of SOFC-HAT combined system.
