两种不同质子交换膜燃料电池性能试验与分析

利用自主开发的100 kW级燃料电池测试平台,对2款车用质子交换膜燃料电池的极化特性曲线、电流密度以及单电池一致性等性能进行了测试,提出了一种评价单电池一致性的方法.研究结果表明,2款质子交换膜燃料电池发动机在上述性能指标上有较大差异;在车载使用条件下,工作压力较高的燃料电池具有更好的环境适应性.

Performance Examination and Analysis of Two Different Proton Exchange Membrane Fuel Cell

Based on the self-designed 100 kW fuel cell test bench,a test is carried out on the polarization curve,current density and single cell consistency of two types of proton exchange membrane fuel cell(PEMFC).A method to evaluate the single cell consistency is put forward.The test results show that there is a great difference between these two PEMFCs in their performances.When applied to automobile,the PEMFC has a better adaptability to the environment under higher pressure operation.
