ABSTRACT:
Solid polymer membranes comprised of a high charge density sulfonated poly (phenylene oxide) blended with poly(vinylidene fluoride) in varied ratios have improved membrane characteristics. These membranes are inexpensive and possess very high ionic conductivity, and thus are suitable for solid polymer 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 performance of these devices.
