Abstract

An aromatic proton conductive polymer, sulfonated polyimide copolymer membrane, was tested in humidity cycling under the conditions simulating fuel cell operation. The membrane was exposed periodically (every 2 min) to dry (nominal 0% relative humidity) and wet (100% relative humidity) at 80 °C, similar to the United States Department of Energy (US DOE) protocol for proton exchange membrane fuel cells. The membrane was durable for 10,000 cycles without mechanical failure. Post-test analyses by ¹H NMR spectra and gel permeation chromatography (GPC) revealed that the membrane was hydrolyzed to some extent during the cycling test while mechanical properties and gas impermeability were only slightly deteriorated.
