We propose a method to evaluate the proton conductivity of ion-conductive polymers, leveraging the flexibility of polymer materials to contribute to the development of flexible, all-solid-state batteries. Focusing on Nafion films on carbon electrodes, we established a technique to measure proton conductivity using impedance spectroscopy. The proton conductivity of Nafion films was found to be dependent on the interface.
