Journal ArticleDOI
Characterization of High‐Surface‐Area Electrocatalysts Using a Rotating Disk Electrode Configuration
Thomas J. Schmidt,Hubert A. Gasteiger,G. D. Stäb,Peter Urban,Dieter M. Kolb,Rolf Jürgen Behm +5 more
TL;DR: In this article, a method for the characterization of the electrocatalytic properties of highly dispersed electro catalysts in a true rotating disk electrode configuration by attaching the catalyst powder on a glossy carbon electrode via a thin Nafion film is presented.
Journal ArticleDOI
Impedance studies on direct methanol fuel cell anodes
TL;DR: In this paper, the processes taking place in direct methanol fuel cell anodes are characterized by ac impedance spectroscopy, and a simple equivalent circuit is used to model this impedance behaviour.
Journal ArticleDOI
Characterization of direct methanol fuel cells by ac impedance spectroscopy
Jens Mueller,Peter Urban +1 more
TL;DR: In this article, the processes taking place in direct methanol fuel cells (DMFC) are characterized by ac impedance spectroscopy under realistic operating conditions, which allows the separate examination of anode kinetics, anode mass transport, cathode kinetic, and membrane conductivity, making it a valuable diagnostic tool for DMFC development.
Journal ArticleDOI
Electro‐oxidation of Dimethyl Ether in a Polymer‐Electrolyte‐Membrane Fuel Cell
Jens Müller,Peter Urban,Wolfgang F. Hölderich,Kevin M. Colbow,Jiujun Zhang,David P. Wilkinson +5 more
TL;DR: In this paper, a mechanism for DME electrooxidation was proposed based on the results of half-cell experiments using cyclic voltammetry combined with gas-chromatographic (GC) analyses of a single direct DME fuel cell.

Method and apparatus for operating an electrochemical fuel cell with periodic reactant starvation
Kevin M. Colbow,Der Geest Marian Van,Cindy J. Longley,Jens Müller,Joy Roberts,Jean St-Pierre,Peter Urban,Regina Wezel,David P. Wilkinson,Jiujun Zhang +9 more
TL;DR: In this paper, an electrochemical fuel cell is operated with periodic oxidant starvation, which may have other beneficial effects at the electrodes, including performance improvements due to water management effects or localized heating effects at starved electrode.
