Title

Development of solid polymer electrolytes for water electrolysis at intermediate temperatures

Abstract

The hydrolytic stability of a number of high-temperature polymers was determined at 200°, 300° and 400°C. None of the better-known ion-conducting polymers, such as perfluorinated alkyl sulfonate and poly(ethylene oxide) were stable at these temperatures. Based on 24 h exposure under steam/H2 and steam/O2 atmospheres at 200°C, liquid crystal polyesters, polybenzimidazoles and some polyimides showed sufficient stability to warrant further study. Polyphenylene sulfides, polysulfones, polyketones and some polyimides showed reasonable stability at 300°C. No candidates were found to be stable under steam/O2 at 400°C, although some were stable under steam/H2 at that temperature. The possibility of converting high-temperature polymers into highly conductive polymer electrolytes is discussed. © 1993.
