HIGHLY FLUORINATED BACKBONE POLYMER ELECTROLYTE MEMBRANE |
摘要 |
A polymer electrolyte membrane is provided having a thickness of 90 microns or less and comprising a polymer, said polymer comprising a highly fluorinated backbone and recurring pendant groups according to the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>YOSO<SUB>2</SUB>-CF<SUB>2</SUB>-CF<SUB>2</SUB>-CF<SUB>2</SUB>-CF<SUB>2</SUB>-O-[polymer backbone] (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where Y is H<SUP>+</SUP> or a monovalent cation such as an alkali metal cation. Typically, the membrane is a cast membrane. Typically, the polymer has a hydration product of greater than 22,000. Typically, the polymer has an equivalent weight of 800-1200. |
