Experimental Investigations on Performance of Proton Exchange Membrane Fuel Cell's Oxidant

分析采用不同氧化剂和改变气体压力对质子交换膜燃料电池性能的影响,用测定电压/电流密度曲线的方法研究了质子交换膜燃料电池的性能特点以及电池温度对电池性能的影响,并对氢-氧和氢-空气燃料电池做了性能对比,实验结果是氧气作氧化剂比空气作氧化剂性能好得多,而且随着温度的增加性能有所改善.压力实验结果是随着气体压力的增大电池性能增强,输出功率增大.

The purpose of this experiment is to analyse performance between different oxidants and changing gas pressure.The performance characteristics of proton exchange membrane fuel cell and the influence of temperature of cell on fuel cell performance have been researched by voltage/current-density experimental method.There was a performance contrast between H2-O2 and H2-air fuel cell.The result is that oxygen oxidant is better than air oxidant on performance of proton exchange membrane fuel cell,and if there is an increase in temperature,then performance rises.The pressure result of experiment is an increase in pressure leads to higher performance and produces higher power.
