摘　　要：建立了燃料电池系统CFD仿真平台,应用该平台对一种采用离心式空压机的燃料电池系统性能进行了仿真研究,并与国内目前采用旋涡式空压机的燃料电池系统性能进行了比较分析。结果表明:采用离心式空压机的燃料电池系统运行范围能够达到常用系统运行范围,且系统效率更高,空气加湿性能更好。A CFD simulation platform for fuel cell system is developed, on which the performance of the fuel cell system with centrifugal compressor is simulated and compared with that of the ordinary fuel cell system using scroll-type compressor. The results indicate that the fuel cell system with centrifugal compressor can attain an operation range as the ordinary system has and is higher in system efficiency and better in humidification performance.
