Title
Development of new proton exchange membrane electrolytes for water electrolysis at higher temperatures
Abstract
This project is an attempt to synthesize and fabricate proton exchange membranes for hydrogen production via water electrolysis that can take advantage of the better kinetic and thermodynamic conditions that exist at higher temperatures. Current PEM technology is limited to the 125-150°C range. Based on previous work evaluating thermohydrolytic stability, several families of polymers were chosen as viable candidates: polyether ketones, polyether sulfones, polybenzimidazoles, and polyphenyl quinoxalines. Representatives of each were converted into ionomers via sulfonation and fashioned into membranes for evaluation. In particular, the sulfonated polyetheretherketone, or SPEEK, was examined by thermoconductimetric analysis and performance tested in an electrolysis cell. Results comparable to commercial perfluorocarbon sulfonates were obtained. © 1998 International Association for Hydrogen Energy.
