Molecular Design Aspect of Anion Exchange Polymer Electrolytes

摘要

Anion exchange polymer electrolytes play an important role both in separator (membrane) and in electrode binder (ionomer). Depending on their role, polymer electrolytes must possess certain properties which are essential to improve the alkaline membrane fuel cell performance & durability. In this study, we will present molecular design aspects of anion exchange polymer electrolytes for the use of membranes and ionomeric binders. In-depth studies on chemical degradation of polyaromatic anion exchange membranes and importance of perfluoirnated structure in the catalyst layer will be discussed in addition to the effects of cation type on chemical degradation and interaction with electro-catalysis.
