BLEND MEMBRANES BASED ON SULFONATED POLY(PHENYLENE OXIDE) FOR ENHANCED POLYMER ELECTROCHEMICAL CELLS

摘要

Solid polymer membranes comprised of a high charge density sulfonated poly(phenylene oxide) blended with poly(vinylidene fluoride) in varied ratio s have improved membrane characteristics. These membranes are inexpensive and possess very high ionic conductivity, and thus are suitable for solid polyme r electrolytes in electrochemical applications, especially for the polymer electrolyte membrane (PEM) fuel cell, the electrolyte double-layer capacitor , and the rechargeable zinc-halide cell. These membranes enhance the performan ce of these devices.
