摘要
为了得到一种车用质子交换膜燃料电池堆的设计方法,以双极板流场内的气体流速、压力控制和气体分布与冷却水分布均匀为目标,研究了流场设计和冷却水流道布置,探讨了燃料电池堆的组装技术,涉及到了定位、预紧力选择以及密封方式的确定。对设计出的燃料电池堆进行稳态和动态实验。结果表明:通过该设计方法得到的燃料电池堆具有良好的稳态性能,并且能够保证动态过程中气体的补充,从而保证了电池堆功率的正常输出,达到了车用燃料电池的要求。
The flow field design and coolant properties of a proton exchange membrane fuel cell （PEMFC） stack for vehicles were studied to evaluate the effect of gas speed and pressure on the bipolar plate% flow field. The assembly of the PEMFC stack is also analyzed including locating, matching, and selecting of assemblies and the sealing. The PEMFC stack was tested in steady state and transient experiments. The results show that the PEMFC stack has excellent performance with enough hydrogen flow so that the stack has normal output during transients which is impprtant for vehicular applications.
