Manabu Tanaka,Keita Fukasawa,Eriko Nishino,Susumu Yamaguchi,Koji Yamada,Hirohisa Tanaka,Byungchan Bae,Kenji Miyatake,Masahiro Watanabe +8 more
TL;DR: A well-controlled multiblock structure was responsible for the developed hydrophobic/hydrophilic phase separation and interconnected ion transporting pathway, and the ionomer membranes showed considerably higher hydroxide ion conductivities, than those of existing anion conductive ionomers.
Journal ArticleDOI
Block Copolymers for Fuel Cells
TL;DR: An overview of the morphology and transport properties of ion-containing block copolymers that have been studied to gain insight into the fundamental behavior of these materials and, in some cases, are targeted toward applications in fuel cells and other electrochemical devices is presented in this article.
Journal ArticleDOI
Highly Stable, Anion Conductive, Comb-Shaped Copolymers for Alkaline Fuel Cells
TL;DR: The results indicated that the C-16 alkyl side chain ionomer had a slightly better initial performance, despite its low IEC value, but very poor durability in the fuel cell.

Water Uptake by and Transport Through Nafion® 117 Membranes
Thomas A. Zawodzinski,C. R. Derouin,Susan D. Radzinski,Ruth J. Sherman,Van T. Smith,T. E. Springer,Shimshon Gottesfeld +6 more
TL;DR: In this article, the diffusion coefficient and relaxation time of water in the membrane and the protonic conductivity of the membrane as functions of membrane water content were measured, and the ratio of water molecules carried across the membrane per proton transported, the electro-osmotic drag coefficient, was determined for a limited number of water contents.
Journal ArticleDOI

Angelika Heinzel,V.M. Barragán +1 more
TL;DR: In this article, the influence of methanol crossover in DMFCs and the effort to get a more methenol-impermeably polymer electrolyte found in the literature is discussed.
Journal ArticleDOI
Mechanism and electrocatalysis in the direct methanol fuel cell
TL;DR: In this paper, a unified treatment of the mechanism of electrocatalysis of methanol oxidation on platinum and platinum-containing alloys is put forward, and the effect of various alloys are shown to be interpretable within this overall model.
