001022606 520__ $$aHydrogen fuel utilization is one of the significant factors for the commercialization of PEMFC in automotive applications. Too low fuel utilisation decreases the driving range and fuel economy. However, too high utilization might lead to localized hydrogen starvation, which significantly reduces the lifetime and performance of the fuel cell system [1]. Hence, advanced diagnostics are needed to detect hydrogen starvation early and during operation [2].In this paper, a commercial MEA is tested under low hydrogen stoichiometry to simulate the spatial anode starvation condition. A newly developed electrochemical impedance spectroscopy (EIS) setup, which could measure up to 1000 impedance values in 1 second, is run in parallel for online characterization. The single cell stack is equipped with a current distribution measurement plate to confirm the starvation condition by the presence of a current deficit area in the anode outlet (Fig. 1). In addition, a novel localized CO stripping method is employed to validate the degradation on the cathode catalyst layer by measuring the localized distribution of the electrochemical active surface area (dECSA).This study shows that EIS spectra are non-sensitive towards hydrogen stoichiometry in the range of sufficient hydrogen supply,
