The anion exchange membrane fuel cells (AEMFCs) have been noticed as the promising power sources. One of the most important components in AEMFC is the anion exchange membranes(AEMs). Recently various materials for AEMs have been investigated for fuel cell applications. Imidazolium-based long alkyl chain multiblock copolymers have drawn much interest due to their well-defined phase separation between hydrophilic and hydrophobic blocks. We report herein the investigation of the effect of block ratio on the phase separation as well as mechanical and electrical properties of the corresponding membranes.
