HIGHLY BASIC IONOMERS AND MEMBRANES AND ANION HYDROXIDE EXCHANGE FUEL CELLS COMPRISING THE IONOMERS AND MEMBRANES

摘要

This invention provides a family of functionalized polymers capable of forming membranes having exceptional OH' ionic conductivity as well as advantageous mechanical properties. The invention also provides membranes including the provided polymers and AEMFC/HEMFC fuel cells including such membranes. In a preferred embodiment, preferred function groups include a quaternary phosphonium. and in a more preferred embodiment the provided polymer is (tris(2,4,6-trimethoxyphenyl) phosphine)3 functionalized phosphonium polysulfone hydroxide.
