Use of Electrochemical Impedance Spectroscopy for the Evaluation of Performance of PEM Fuel Cells Based on Carbon Cloth Gas Diffusion Electrodes

<div>Sum of the charge transfer (<i>R</i><sub>p</sub>) and the mass transfer resistances (<i>R</i><sub>d</sub>) at a high inlet gas flow rate (a)—0.5/2 Nl/min H<sub>2</sub>/air—and at a low inlet gas flow rate (b)—0.2/1 Nl/min H<sub>2</sub>/air.</div>
