Journal ArticleDOI
Oxygen Reduction Kinetics on a Platinum RDE Coated with a Recast Nafion Film.
TL;DR: In this paper, the authors measured currents of the oxygen reduction reaction (ORR) at a Pt RDE coated with a recast Nafion film yield the permeability of O/sub 2/ through such films.
Journal ArticleDOI
A shorted membrane electrochemical cell powered by hydrogen to remove CO2 from the air feed of hydroxide exchange membrane fuel cells
Journal ArticleDOI
Thin‐layer composite enzyme electrodes for glucose determinations
Thomas A. Zawodzinski,Carmen Campbell,John Davey,Shimshon Gottesfeld,James Serach,Mahlon S. Wilson,Judith Rishpon +6 more
TL;DR: In this paper, a composite active layer consisting of Nafion, glucose oxidase, and carbon-supported platinum particles was used for amperometric glucose sensitive electrodes with an active layer composed of carbon dioxide and carbon dioxide.
Journal ArticleDOI
The physical and chemical state of phosphoric acid fuel cell assemblies after long term operation: surface and near-surface analysis
TL;DR: In this paper, an attempt was made to correlate performance losses with materials compatibility and compositional changes in phosphoric acid fuel cell (PAFC) electrode assemblies as a function of operation time, and the most pronounced change in cell composition detected following stack operation for 5000 and 16 000 h was the increase in Pt/C ratio, that was related to loss of carbon from the cathode electrocatalyst.
Journal ArticleDOI
Ellipsometric studies of conducting polymers
TL;DR: In this paper, ellipsometric measurements on films of polyaniline grown galvanostatically on platinum electrodes in HCl solutions were reported. And they were also studied while undergoing electrochemical conversion between the reduced (insulating) and oxidized (conducting) forms induced by potential cycling.
