A comparative study of various gas diffusion layersGas diffusion layer in theMembrane membrane-electrodeElectrode assembly was conducted. It was shown that among the studied materials, the best characteristics in terms of voltage and power were demonstrated by the Toray TGP-H-060 GDL. Variation of the humidity of the supplied gasses showed that in some cases lower humidity allowed increasing the specific characteristics of the MEA. Measurements of the charge transfer resistance byImpedance spectroscopy impedance spectroscopy methods showed that at a voltage of 800 mV, the lowest charge transfer resistance was demonstrated by the MEA with AvCarb P75T and Toray TGP-H-060.
