Transport properties of proton-exchange membranes: effect of supercritical-fluid processing and chemical functionality
(2010)
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 ...
Novel sulfonated ether based block copolymer ionomers as proton exchange membranes for fuel cells applications
(2017)
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 ...
Poly(styrene-isobutylene-styrene) nanocomposite membranes for fuel cell devices and specialty separation applications
(2018-05)
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 ...
