The most significant proton exchange membrane(PEM) development is the introduction of Nafion by Dupont in 1968 based on perflourosulfonic acid. However, perflourinated membranes are expensive due to the toxic and complicated production process and have high MeOH cross-over. In this study, well-defined poly(2,6-dimethyl -1,4-phenylene oxide)-g-poly(vinylbenzyl phosphoric acid) (PPO-g-PVBPA), was synthesized by reversible addition fragmentation chain transfer(RAFT), phosphorylation, and hydrolysis. Then it was converted into fuel cell membrane. The membrane was characterized by ion conductivity ,water uptake, MeOH permeability, etc. Other characters for fuel cell membrane such as phase separation behavior and conductivity etc. will be discussed. |
