摘要：

针对增压型熔融碳酸盐燃料电池(MCFC)与现有微型燃气轮机(MGT)设计的混合动力系统，分析了在部分负荷运行时MCFC的特性；在MCFC建模过程中，考虑了电流密度和电池工作温度等参数的影响，并将模拟结果与其实验数据进行对比；应用压气机和透平的特性曲线建立了MGT在非设计工况下的分析模型；提出了4种不同的控制方式，以控制系统的部分负荷运行，并应用所建模型分析了系统中MCFC在不同控制方式下的特性.结果表明：通过有效的控制手段以保持较高的MCFC工作温度，可使MCFC在部分负荷运行时的效率高于设计点值；MCFC的性能对混合动力系统影响很大；在部分负荷运行时需要维持较高的电池工作温度以提高系统性能.

Abstract:

The molten carbonate fuel cell (MCFC) performances of a pressured MCFC/MGT hybrid system using a fixed micro-gas turbine (MGT) design were analyzed for off-design operation with different control methods. The effects of current density and MCFC temperature were considered for the MCFC modeling, and the modeling and experimental result were comparied. The off-design operation of the MGT was modeled by the performance characteristics of the compressor and turbine. Four control methods were mentioned for the part-load operation of the hybrid system, and the performances of MCFC were analyzed for the different methods using the system model. The results show that the efficiency of MCFC at partload operation can be higher than the design value by using the control method. The performance of MCFC has great effects on the system, the system performance can be improved by maintaining the MCFC operation temperature.

Key words: molten carbonate fuel cell (MCFC), micro-gas turbine (MGT), hybrid power system
