摘　　要：建立了质子交换膜燃料电池(PEMFC)堆的热力学分析模型,研究了运行温度、气体分压和阳极流量等工作参数对燃料电池堆能量效率和火用效率的影响。结果表明:对气体加压,能提高热力学能效率和火用效率;温度升高时,系统性能无明显变化;阳极流量增加时,系统的热力学能效率和火用效率有所降低。The thermodynamic model of proton exchange membrane fuel cell （PEMFC） stack was established, and the effect of operating temperature, gas pressure and anode flow parameters to the energy efficiency and exergy efficiency of fuel cell stack was analysised. The results showed that： when the gas pressure rised, the thermodynamic energy efficiency and exergy efficiency could increase; and the temperature rised, no significant changes in system performance; when anode flow rate increased, the thermodynamic energy efficiency and exergy efficiency of system decreased.
