Abstract： This paper addressed the design, offdesign and startup analysis of a hybrid system based on the coupling of a microgas turbine and pressured molten carbonate fuel cell. The design of hybrid system was based on a commercially available microgas turbine for the commercialization. The partload performances were compared considering different control methods. The system startup method was proposed and the possible problems and system performances for the startup process were studied. The results show that the performance is poorer for the system designed based on MGT than MCFC. The system performances can be improved by keeping the operating temperature as high as possible for the part load operation. This system is not suitable for frequent startup considering the characteristics of MCFC.
