Kinetics and Transport at AMTEC Electrodes: II . Temperature Dependence of the Interfacial Impedance of Na(g)/Porous Mo/Na‐Beta′ Alumina
Autor: Barbara Jeffries-Nakamura, C. P. Bankston, Roger M. Williams, M. L. Underwood, J. T. Kummer
Publikováno v: Journal of The Electrochemical Society. 137:1716-1723
The exchange current, transfer coefficient, mass-transport parameters, and electrode capacitance at the Na(g)/porous Mo/Na-Beta-double prime alumina solid electrolyte (BASE) phase boundary have been evaluated from 740 to 1220 K. The transfer coeffici

Kinetics and Transport at AMTEC Electrodes: I . The Interfacial Impedance Model
Autor: Barbara Jeffries-Nakamura, Roger M. Williams, J. T. Kummer, C. P. Bankston, M. E. Loveland, M. L. Underwood, H. Leduc
Publikováno v: Journal of The Electrochemical Society. 137:1709-1716
Mixed mass-transport and kinetic control of sodium ion reduction at porous inert electrodes on sodium beta-double-prime alumina solid electrolyte (BASE) ceramic in a high-temperature electrochemical cell has been observed and modeled. The high ionic

A chemically regenerative redox fuel cell. II
Autor: Djong-Gie Oei, J. T. Kummer
Publikováno v: Journal of Applied Electrochemistry. 15:619-629
A novel chemically regenerative redox fuel cell is described. The electrode reactions are based on the following redox reactions: cathodic reaction: anodic reaction: VO 2 + +2H++e → VO2++H2O (E 0 ∼+1V), SiW12O 40 5− → SiW12O 40 4− +e (E 0

Use of noble metals in automobile exhaust catalysts
Autor: J. T. Kummer
Publikováno v: The Journal of Physical Chemistry. 90:4747-4752
This is a review of recent literature involving laboratory work on catalytic reactions of interest in automobile exhaust purification. The review is concerned with the noble metals Pt, Pd, and Rh, the oxidation of CO and hydrocarbons, the reduction o

Exchange between N230 and N228 over Iron Catalysts
Autor: Paul H. Emmett, J. T. Kummer
Publikováno v: The Journal of Chemical Physics. 19:289-292
The rates of exchange between N228 and N230 obtained on doubly‐ and singly‐promoted iron catalysts is of the right order to be accounted for by assuming that all nitrogen evaporating from the surface of the catalyst is completely equilibrated wit
