This invention relates to novel ion-conducting materials suitable for use as solid polymer electrolyte membranes in electrochemical applications including fuel cell systems. More specifically, these novel ion-conducting polymers are based on sulfonated polyaryletherketone polymers or sulfonated polyphenylsulfone polymers, including copolymers, or blends thereof. The present invention also describes novel processes for producing these ion- conducting materials.
La présente invention concerne des matériaux conducteurs d'ions convenant comme membranes d'électrolytes polymères pour l'électrochimie et notamment les piles à combustible. L'invention concerne plus particulièrement des matériaux conducteurs d'ions à base de polymères de polyaryléthercétones ou de polyphénylsulfones sulfonés, y-compris de certains de leurs copolymères et de leurs mélanges. L'invention concerne également la production de tels matériaux conducteurs d'ions.
