Polybenzimidazole based polymer and method for preparing the same

摘要

Disclosed is a polybenzimidazole based polymer, which can be used at high temperature under no-humidification conditions for preparing a fuel cell, in particular, a fuel cell membrane instead of the existing Nafion type perfluorosulfonated polymers, with which it is easy to increase a doping level, and also, which exhibits an excellent mechanical strength, further, which is inexpensive. Further, disclosed is a method for preparing the polybenzimidazole based polymer.
