Abstract
Considering the feature of both of a gas turbine and a fuel cell, we designed the new MCFC-GT hybrid system. Using oxygen-blown semi-closed configuration, the combination of MCFC and combustion turbine became possible. In addition, adopting this system enables not only the carbon dioxide recovery but also to increase the MCFC output power density. As a result of optimization based on heat and mass balance calculation, the sending-end efficiency of this system proved to be over 65%.
