摘　　要：质子交换膜燃料电池(PEMFC)是一种高效、零污染的发电技术,能够将氢气的化学能通过电化学反应直接转化为电能,在家用热电联产、备用电源、新能源汽车等领域具有广阔的应用前景。电池堆是PEMFC系统的核心部件,系统结构及集成工艺对燃料电池堆性能影响显著。本文针对PEMFC系统结构、气路子系统、增湿子系统、热管理子系统、控制子系统分别进行了阐述,并实验测试了自消耗情况以及系统启动温度、系统稳定运行温度等因素变化时电池堆的电流-电压曲线,获得了PEMFC性能变化规律。实验结果表明:PEMFC系统的启动温度和稳定运行温度对电池性能有较为显著的影响,当系统启动温度约为25℃、稳定运行温度为50~60℃时,电池堆性能达到最优值。该结论可为优化质子交换膜燃料电池堆性能、提高电池系统运行稳定性提供依据。The proton exchange membrane fiiel cell(PEMFC)is a clean and efficient power generation technology,which can directly convert the chemical energy of hydrogen into electricity by electrochemical reaction.The PEMFC has a wide application prospect in the fields of domestic co-generation,standby power supply and new energy automobile and so on.The fuel cell stack is the core component of the PEMFC system,and the system structure and integration process have a significant effect on the performance of fuel cell stack.This paper individually expatiates on the structure of the PEMFC system,gas subsystem,wetting subsystem,thermal management subsystem and control subsystem.The current-voltage experiment is carried out on the fuel cell stack when factors change such as the self-consumption,the starting temperature and the stable operation temperature.Then the performance change rules of the fuel cell stack are obtained.The experimental results show that,the system starting temperature and the stable operation temperature of the PEMFC system have a significant effect on its performance.When the system starting temperature is around 25°C and the system stable operation temperature is 50~60°C,the fuel cell stack achieves the optimal performance.This conclusion can provide a basis for optimizing the performance of the PEMFC and improving the stability of the battery system.
