Hyperbranched polymer electrolyte membrane

The application tests of hyperbranched polymers have namely focused on their employment as non-linear optical polymers, polymer electrolytes, biomaterials, supramolecular components (nanomaterials), photolithographic materials, coatings, modifiers and additives and polymeric membranes so far [3].

Abstract This chapter describes the apphcation of hyperbranched polymer-based electrolyte membranes for high temperature fuel cells. Hyperbranched polymers with a sulfonic acid group or a phosphonic acid one as a proton source were synthesized and the proton conductivity, thermal property and fuel cell performance of their polymers and crosslinked membranes were investigated. The concept of the proton conduction coupled with the polymer chain motion was proposed for high temperature fuel cells. [Pg.524]
