Infrared Analysis of Nafion 424 membrane for carboxylate presence


EMSL Project ID
2268

Abstract

The supporting grid in Nafion 424 membrance can, if overheated, release HF. Since the pitting corrosion appears to match the mesh grid, this could explain the observed corrosion in CerOx materials. We plan to use XPS and TOF-SIMS to determine the presence or absence of carboxylate. Two samples will be examined. One unused sample of Nafion 424 and one which was taken from the system.
