摘要: 为故障诊断和健康度(SOH)估计,开发了一种不使用单一电池电压测量(CVM)的质子交换膜燃料电池(PEMFC) 的监测技术——“AVL THDA”。该技术运用谐波偏移、电抗谱技术,监测电池组的临界电压迁移,以保证可靠的运行状态;运行状态被在线评估,并被分成膜干涸、液体水滴和介质供应不足等几类。电池系统控制器可以立即启动计数测量,以防止电池的退化;考虑到了对于电池的长期影响,以及生命周期评估。该技术可以被集成到现有的燃料电池系统构件中,因此具有经济应用的前景。

Abstract: An advanced version, AVL THDA, was developed to monitor the proton exchange membrane fuel cell (PEMFC) without using single cell voltage measurement (CVM) fault diagnosis and evaluate State of Health (SOH). The AVL THDA detects critical voltage drifts on cell level to ensure reliable operating conditions using harmonic distortion and electrical impedance spectroscopy. Detected critical operating conditions are assessed online and classified into membrane dry-out, liquid water droplets and low media supply issues. Thus, a system controller can immediately initiate counter measures preventing stack degradation. Taking into account long term effects in the fuel cell, also life time estimation is considered. The technology is capable of being fully integrated into existing fuel cell system components, therefore, has potential of cost efficient application.

Key words: fuel cell (FC) monitoring, proton exchange membrane fuel cell (PEMFC), life time measurement, online diagnostics, ?harmonic distortion, electrical impedance spectroscopy
