Research Progress of Online Monitoring Methods for Proton Exchange Membrane Fuel Cells

质子交换膜燃料电池作为一种高效、无污染的新一代发电技术在近年来得到广泛关注,但是其寿命问题依然严重制约其商业应用。通过对燃料电池状态进行在线监测来实现电池的快速故障诊断,是延长电池寿命的极有效的途径之一。本文对近年来质子交换膜燃料电池在线监测方向的文章进行了总结,并按照故障检测方法(包括极化曲线、循环伏安法、电化学阻抗谱等)进行分类讨论。同时,根据实际应用情况将单一检测方法和多种结合检测方法进行文献综述。另外,在总结现有的在线监测方法的基础上,本文提出了未来燃料电池在线监测需要解决的问题并进行展望。

Proton exchange membrane fuel cells,a new generation of efficient and pollution-free power generation technology,have received widespread attention in recent years.However,their limited battery life severely restricts their commercial applications.An effective strategy to extend the battery life is to rapidly diagnose faults in the fuel cell via monitoring its status online.This review summarizes recent developments in the online monitoring of proton exchange membrane fuel cells,and classifies and discusses them based on fault detection methods,including polarization curves,cyclic voltammograms,and electrochemical impedance spectra,and so on.Single and multiple combined detection methods are reviewed based on practical applications.In addition,the current limitations of each online monitoring method and the future prospects of online monitoring of fuel cells are discussed on the basis of existing on-line monitoring methods.
