In this presentation, two important pitfalls ocuring during the analysis of electrochemical impedance spectra (EIS) of polymer electrolyte fuel cells (PEFCs) are discussed. Based on very simple considerations, some commonly found interpretation statements are identified as wrong. A comprehensive review of the papers published during the year 2018 using EIS in PEFC research show that such wrong statements are not occasional, but frequently occurring in the peer reviewed literature. At the end of the presentation, solution are proposed to increase the awareness to the risks of wrong EIS interpretations.
