POLYELECTROLYTE MEMBRANE FOR ELECTROCHEMICAL APPLICATIONS, IN PARTICULAR FOR FUEL CELLS

摘要

A polyelectrolyte membrane may include at least one styrene polymer or copolymer having a syndiotactic configuration and having sulfonic groups. The at least one styrene polymer or copolymer may be made in the form of a film in clathrate form. The film may include less than about 0.1% sulfonate groups of —SO₃⁻Y⁺ general formula, in which Y may be a monovalent metal cation.
