Abstract: Electrochemical Impedance Spectroscopy (EIS) is a suitable and powerful diagnostic testing method for PEMWE (polymer electrolyte or proton exchange membrane water electrolysis) cell because it is non-destructive and provides useful information about fuel cell performance and its components. It can principally be used in PEMWE diagnosis including optimization of MEAs (membrane electrode assemblies). The EIS technique measures the frequency dependence of the cell impedance applying a small sinusoidal AC current (or voltage) as a perturbation signal while measuring the voltage (or current) response. EIS can provide useful information on voltage losses in PEMWE. This testing procedure is a general characterization method that is used in research and development of the PEMWE single cells. The test can be used as a baseline measurement for the qualification of a PEMWE and its components.
