We present in-depth profiling by micro FTIR of cross sections for Nafion 115 membranes in membrane-electrode assemblies (MEAs) degraded during 52 or 180 h at open circuit voltage (OCV) conditions, 90 °C and 30% relative humidity. Analysis of optical

The most commonly used proton exchange membranes (PEMs) for hydrogen and direct methanol fuel cells are the perfluorosulfonic acid ionomers (PFSA) such as Nafion, which are based on a Teflon-like backbone with side chains containing sulfonic groups.

We present the effect of the degree of sulfonation (DS) and water content on the phase separation in sulfonated poly(ether ether ketone) (SPEEK) ionomers, using the method of spin probe electron spin resonance (ESR). The ionomer contained the nitroxi

We report attempts to synthesize and to study the stability of anion exchange membranes (AEMs) from the perfluorinated 3M membrane precursor having terminal sulfonyl fluoride, –SO2F, groups in the side chains of the backbone. The precursor was obta

We present experiments in a fuel cell (FC) inserted in the resonator of the electron spin resonance (ESR) spectrometer, which allowed separate monitoring of radical formation at anode and cathode sides. The in situ FC was operated at 300 K under clos
