| Research Abstract |
Nafion ionomer is extensively used as a proton exchange membrane (PEM) for a polymer electrolyte fuel cell (PEFC). In the present study, attenuated total reflection infrared (ATR-IR) spectra of a Nafion membrane were collected under a potential sweep condition. The obtained spectra were analyzed by perturbation-correlation moving-window two-dimensional (PCMW2D) correlation spectroscopy. Hydration structure of a Nafion membrane was discussed in detail.
