Nafion® membranes commonly used in direct methanol fuel cells (DMFC), are tipically limited by high methanol permeability (also known as the cross-over limitation). These membranes have phase segregated sulfonated ionic ...

This investigation studied the morphology, hydration, and transport properties of different membranes for direct methanol fuel cell (DMFC) applications. First, sulfonated poly(ether ether ketone) (SPEEK) membranes were ...

Ionic domains were incorporate into sulfonated poly(styrene–isobutylene–styrene) (SO3H SIBS) in an effort to improve the transport properties of the functionalized aromatic block copolymer. The resulting polymer nanocomposite ...
