Enhancement of the Electroreduction of Oxygen on Pt Alloys with Fe, Ni, and Co
TL;DR: In this article, an enhancing mechanism for the ORR based on an increased d−electron vacancy of the thin Pt surface layer caused by underlying alloy was proposed. But this mechanism was only applied to the perchloric acid solution.
Journal ArticleDOI
Electrocatalysis by ad-atoms: Part II. Enhancement of the oxidation of methanol on platinum by ruthenium ad-atoms
Masahiro Watanabe,Satoshi Motoo +1 more
TL;DR: The ad-electrode has the same electrocatalytic characteristics as the alloy electrode for the oxidation of methanol on the Ru-Pt catalyst system as discussed by the authors.
Journal ArticleDOI
Electrocatalysis by ad-atoms: Part III. Enhancement of the oxidation of carbon monoxide on platinum by ruthenium ad-atoms
Masahiro Watanabe,Satoshi Motoo +1 more
TL;DR: In this paper, the authors found that carbon monoxide oxidation on platinum by ruthenium ad-atoms was found to take place in two θ Ru regions; one by the increase of ( n Pt−Ru ) av and another by an increase of n Ru−Ru av, as expected from the standpoint of the bi-functional theory proposed by the authors.
Journal ArticleDOI
Aliphatic/Aromatic Polyimide Ionomers as a Proton Conductive Membrane for Fuel Cell Applications
TL;DR: Ionomer 1 membrane showed comparable performance to Nafion and was durable for 5000 h without distinct degradation, and microscopic analyses revealed that smaller (<5 nm) and well-dispersed hydrophilic domains contribute to better proton conducting properties.
Journal ArticleDOI
Anion conductive block poly(arylene ether)s: synthesis, properties, and application in alkaline fuel cells.
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.
