Spatially Resolved Current Density and Electrochemical Impedance Spectroscopy in PEM Fuel Cells

This dataset contains the raw data underlying the results presented in the open-access paper “Spatially Resolved Current Density Distribution and Electrochemical Impedance Spectroscopy in PEM Fuel Cells” by Fensterle et al. in the Journal Fuel Cells (DOI:10.1002/fuce.70057). The measurements were conducted on a 10-cell short stack of the generic HyFaB stack within the framework of the European project RealHyFC (Grant Agreement No. 101111904). The dataset includes polarization curves together with the corresponding spatially resolved current density distributions under nominal RealHyFC operating conditions, as well as results from a sensitivity study including variations in temperature, pressure, humidity, and stoichiometry. In addition, the dataset contains electrochemical impedance spectroscopy (EIS) measurements both on cell level and spatially resolved. The corresponding operating conditions, measurement methods, and further information regarding data evaluation and interpretation are described in the open-access publication mentioned above.
