Study of water content properties in anion exchange membranes for fuel cell applications

In current study, anion exchange membranes were synthesized by chloromethylation, amination and alkalization. These membranes are based on polysulfone and functionalized with aminegroups (trimethylammonium and 1,6-tetra hexanediamine). 1,6-tetra hexanediamine not only has been used as amination agent, but also acts as crosslinker in membrane structure. The water content properties such as swelling ratio, water uptake and hydration number were determinedfor the prepared membranes. The membrane with crosslinked structure shows enhanced water content properties and better stability. Therefore this membrane can be good candidate for solid alkaline fuel cell applications.
