In this research, deep eutectic solvents (DESs) were prepared and employed as the electrolyte in Nafion membranes. Different factors, such as the water content and Nafion counterions (H + , Li + , Na + and K + ), which could influence the PEM performance, were evaluated. The obtained results showed...
