英文摘要：

Abstract： The reaction performance and influencing factors of catalytic combustor in the molten carbonate fuel cell/micro-gas turbine （MCFC/MGT） hybrid system were studied, and a hybrid system was designed based on the commercial gas turbine. The combination of numerical simulation and experimental study was used to study the catalytic combustor. The plug flow reactor model and detailed reaction mechanism of CH4 on Pt were used for the numerical simulation, and reaction performances of 3 different catalysts were studied in the experimental study. The design point parameters of the hybrid system were identified based on the commercial gas turbine, using the fuel cell temperature as the limiting condition. The results show that the model created can reflect the characteristics of the catalytic combustion burner, the reaction activi- ty of the perovskite and metal oxide catalyst is poorer than the noble metal catalyst. Though the efficiency of the system based on the commercial gas turbine is lower, this design is more practical.
