Ordered Ternary Fuel Cell Catalysts Containing Platinum And Cobalt And Method For Making The Catalysts
US Patent:
4677092, Jun 30, 1987
Filed:
Dec 23, 1985
Appl. No.:
6/812106
Inventors:
Francis J. Luczak - Glastonbury CT
Douglas A. Landsman - West Hartford CT
Douglas A. Landsman - West Hartford CT
Assignee:
International Fuel Cells Corporation - South Windsor CT
International Classification:
B01J 2118
B01J 2364
B01J 2389
B01J 2364
B01J 2389
US Classification:
502185
Abstract:
A ternary alloy catalyst for the electrochemical reduction of oxygen is disclosed. Various methods of making the catalyst are developed. The catalyst has an ordered structure which improves stability and the specific activity of the catalyst.
Method For The Electrochemical Production Of Adiponitrile Using Anodes Having Nico.sub.2 O.sub.4 Catalyst
US Patent:
4596638, Jun 24, 1986
Filed:
Apr 26, 1985
Appl. No.:
6/727472
Inventors:
John C. Trocciola - Glastonbury CT
Douglas A. Landsman - Hartford CT
Douglas A. Landsman - Hartford CT
Assignee:
International Fuel Cells Corporation - South Windsor CT
International Classification:
C25B 300
US Classification:
204 73A
Abstract:
Anodes having NiCo. sub. 2 O. sub. 4 catalyst used in the electrohydrodimerization of acrylonitrile to adiponitrile result in anode voltage requirements of less than about 2000 millivolts at 100 milliamperes per square centimeter of anode area. Typically, oxygen evolving anodes comprised of lead or carbon steel are utilized in the hydrodimerization of acrylonitrile to adiponitrile resulting in high voltage requirements. Anodes containing NiCo. sub. 2 O. sub. 4 catalyst require substantially reduced voltages and perform well in the conventional electrochemical adiponitrile production environment.
Method For Making Ternary Fuel Cell Catalysts Containing Platinum Cobalt And Chromium
US Patent:
4613582, Sep 23, 1986
Filed:
Jan 30, 1984
Appl. No.:
6/575360
Inventors:
Francis J. Luczak - Glastonbury CT
Douglas A. Landsman - West Hartford CT
Douglas A. Landsman - West Hartford CT
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B01J 2118
B01J 2364
B01J 2386
B01J 2364
B01J 2386
US Classification:
502185
Abstract:
An improved ternary noble metal-containing, alloy catalyst which has a catalytic activity for the electrochemical reduction of oxygen greater than two and one-half times that of the supported unalloyed noble metal alone. In addition, a disclosure of the method of preparing said catalyst is by intimately contacting two metallic elements with a supported noble metal, then heating this material to form the ternary alloy catalyst. This catalyst has particular utility for the electrochemical reduction of oxygen which makes it particularly useful as a cathode in acid fuel cells. The preferred embodiment of this catalyst is finely divided platinum alloyed with chromium and cobalt supported on an electrically conductive carbon-black support material.
Electrochemical Cell Electrodes Incorporating Noble Metal-Base Metal Alloy Catalysts
US Patent:
4192907, Mar 11, 1980
Filed:
Jul 3, 1978
Appl. No.:
5/922003
Inventors:
Vinod M. Jalan - Manchester CT
Douglas A. Landsman - West Hartford CT
John M. Lee - West Hartford CT
Douglas A. Landsman - West Hartford CT
John M. Lee - West Hartford CT
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
H01M 808
US Classification:
429 40
Abstract:
A novel and improved fuel cell electrode includes a finely divided noble metal-base metal alloy catalyst. The catalytic activity of noble metal in the electrode is greater than the catalytic activity of the same unalloyed noble metal. Theoretically any base metal may be advantageously alloyed with the noble metal and will yield improved catalytic activity. Preferably the finely divided alloy is supported.
Precisely-Structured Electrochemical Cell Electrode And Method Of Making Same
US Patent:
3956014, May 11, 1976
Filed:
Dec 18, 1974
Appl. No.:
5/533917
Inventors:
Douglas A. Landsman - West Hartford CT
Edward I. Thiery - Winsted CT
Edward I. Thiery - Winsted CT
Assignee:
United Technologies Corporation - East Hartford CT
International Classification:
H01M 400
H01M 404
H01M 404
US Classification:
136 86D
Abstract:
An electrochemical cell electrode, having clearly segregated and structured hydrophobic gas channels and electrolyte-filled catalyst channels is provided in which the size and shape of the various passages are such that they offer little resistance to the passage of reactants and products. The electrode consists of alternate layers of porous hydrophobic material and porous hydrophilic catalyst-containing material. The electrode is formed by first depositing the alternate layers of materials and then cutting the structure in a plane at right angles to the plane of deposition at a thickness equal to that of the end product. Electrodes of varying size can be constructed of panels so produced.
