From the viewpoint of the intercrossing of disciplinary areas, this project studies the integration mechanism and design basis of Molten Carbonate Fuel Cell(MCFC) hybrid power system with CO2 capture.Firstly,the direct work conversion mechanism and the characteristics of CO2-concentration of MCFC system are investigated. The effects of the key operating parameters on the MCFC performance are revealed. The integration mechanism and method between MCFC with different thermal systems according to the different components of exhausted gases from the anode and cathode are explored. In order to reduce the energy consumption of CO2 compression and liquefaction, a new way to liquefy CO2 by integrating the refrigeration process drove by the waste heat in MCFC system is proposed. In order to use the waste heat efficiently, thermal cycle system will be optimized.The integration mechanism and coupling characteristics among the MCFC process, CO2 concentration, separation,liquefaction process and the conventional thermal cycle systems are deeply studied. Then, the new MCFC hybrid sytems with CO2 capture are proposed and the new ways to capture CO2 with lower energy consumption from power systems are explored. Except for the theoretical research, this project will do some experimental research on the unit cell of MCFC, which will test the CO2 transfer and utilization ratio in the cathode of MCFC and investigate the correlations between the key operating parameters and the cell performance. The experiment will provide the key data for the system integration and verify the theoretical models. The research achivements of this project will provide the design theory basis for new hybrid power system with the higher efficiency and lower CO2 emission, also provide a new way and idea for realizing the strategy of energy-saving and pollution emission reduction in our country.
