采用非线性频响分析（NFRA）对差分H2/H2电池中PEMFC阳极CO中毒进行了分析。这种特殊的实验设置排除了潜在的掩蔽效应，强调了CO中毒的主要机制，并使简化的建模方法成为可能。采用稳态极化、EIS和NFRA等方法研究了CO中毒的主要特征。NFRA光谱中CO中毒的主要特征可以作为诊断目的的“指纹”。
Anodic CO poisoning of a PEMFC was analysed by nonlinear frequency response analysis (NFRA) in a differential H2/H2 cell. This special experimental setup excluded potential masking effects, emphasised the main mechanism of CO poisoning and made a simplified modelling approach possible. The main features of CO poisoning were investigated by means of steady state polarisation, EIS and NFRA. The main characteristics of CO poisoning in the NFRA spectra can be used as a “fingerprint” for diagnostic purposes.
