Journal ArticleDOI
Enhanced Performance of a Sulfonated Poly(arylene ether ketone) Block Copolymer Bearing Pendant Sulfonic Acid Groups for Polymer Electrolyte Membrane Fuel Cells Operating at 80% Relative Humidity
TL;DR: The atomic force microscopy image demonstrated that number of ion transport channels is increased with increase in the length of hydrophilic oligomer in the main chains, and the morphology is proved to be related to the proton conductivity.
Journal ArticleDOI
Graphene-mediated organic-inorganic composites with improved hydroxide conductivity and outstanding alkaline stability for anion exchange membranes
TL;DR: A series of composite membranes for application as anion exchange membranes were prepared by introducing various amounts of reduced graphene oxide (rGO) into chloromethylated poly(arylene ether ketone) (CM-PAEK), followed by quarternization and anionization.
Journal ArticleDOI
Improved electrochemical performance of composite anion exchange membranes for fuel cells through cross linking of the polymer chain with functionalized graphene oxide
TL;DR: In this paper, quaternary ammonium functionalized graphene oxide (Q-GO) was introduced into quaternized poly(arylene ether) (QPAE) random copolymer.
Journal ArticleDOI
Effect of functionalized SiO2 toward proton conductivity of composite membranes for PEMFC application
Journal ArticleDOI
Enhanced ion conductivity of sulfonated poly(arylene ether sulfone) block copolymers linked by aliphatic chains constructing wide-range ion cluster for proton conducting electrolytes
TL;DR: A series of sulfonated poly(arylene ether sulfone) block copolymers with aliphatic chains (SPAES-LA) to lend structural flexibility in the polymer backbone have been synthesized to prepare proton exchange membranes (PEMs) showing improved electrochemical performance and dimensional/oxidative stabilities.
