We synthesized a novel monomer with four amine groups which were derivatized to ammonium functional groups. Using this monomer, we easily synthesized poly(arylene ether sulfone)s which conduct hydroxyl ions. This direct synthetic method can control the exact amount of quaternary ammonium hydroxide groups in the polymer structure. The polymers were characterized by NMR, thermogravimetric analysis, water uptake, conductivity, and cell performance. In a solid alkaline exchange membrane fuel cell test, a maximum power output of 77 mW cm(-2) was achieved using hydrogen and oxygen. Copyright (c) 2014, Hydrogen Energy Publications, LLC.
