Abstract
This paper evaluates electrochemical noise (EN) technique as a possible tool for the diagnosis of Proton Exchange Membrane Fuel Cells (PEMFC) during operation. EN was employed to survey PEM single cell under various operating conditions at different humidification levels so as to focus on flooding or drying tendencies.Datawas investigated in the frequency domain by means of power spectrum densities that showed to be sensitive to changes in the PEMFC operating conditions. EN seems an interesting way for an innovative and non-invasive on-line diagnosis tool.
