Assessing cell polarity reversal degradation phenomena in PEM fuel cells by electrochemical impedance sectroscopy

Electrochemical impedance spectroscopy (EIS) is identified as one of the most promising in-situ diagnostics tools available for assessing fuel cell ageing and degradation. In this work, the degradation phenomena caused by cell polarity reversal due to fuel starvation of an open cathode 16 membrane e...
