Three-Electrode Fuel Cell
US Patent:
6756141, Jun 29, 2004
Filed:
Dec 28, 2001
Appl. No.:
10/028710
Inventors:
Michael A. Miller - San Antonio TX
Craig M. Wall - San Antonio TX
Craig M. Wall - San Antonio TX
Assignee:
Southwest Research Institute - San Antonio TX
International Classification:
H01M 804
US Classification:
429 22, 296235, 2042301, 205343
Abstract:
A fuel cell includes an anode electrode, a cathode electrode, and a third electrode interposed between the anode and the cathode electrodes. The third electrode preferably includes an electrically conductive component. The third electrode preferably includes a metallic and a polymer grid and/or a conducting polymer. The third electrode may be used to control processes of the anode and/or the cathode electrodes. The third electrode may also be used to monitor the health of any component of the fuel cell.
Cylindrical Proton Exchange Membrane Fuel Cells And Methods Of Making Same
US Patent:
6001500, Dec 14, 1999
Filed:
Jun 5, 1997
Appl. No.:
8/869795
Inventors:
Edward Albert Bass - San Antonio TX
Patrick Martin Merritt - San Antonio TX
Christopher Alan Sharp - San Antonio TX

International Classification:
H01M 810
US Classification:
429 31
Abstract:
The present invention provides a method of manufacturing a cylindrical fuel cell comprising: providing an anode comprising a substantially solid cylindrical porous conductive matrix, said anode having an anode outer surface; intimately contacting a first proton exchange catalyst with said anode; conforming around and in intimate contact with said anode outer surface an inner polymer electrolyte membrane comprising a membrane outer surface and a membrane inner surface, wherein said membrane inner surface defines a tubular compartment and ionically communicates with said first proton exchange catalyst; providing a source of hydrogen gas in fluid communication with said first proton exchange catalyst; and, disposing around and in ionic communication with said membrane outer surface a cathode comprising a catalytically effective amount of a second proton exchange catalyst.
Autoradiography-Based Differential Wear Mapping
US Patent:
8050489, Nov 1, 2011
Filed:
Jul 20, 2007
Appl. No.:
11/781046
Inventors:
Douglas C. Eberle - San Antonio TX, US
Craig M. Wall - San Antonio TX, US
Martin B. Treuhaft - San Antonio TX, US

Assignee:
Southwest Research Institute - San Antonio TX
International Classification:
G06K 9/00
US Classification:
382149, 250582, 250583
Abstract:
Methods and systems for the differential wear mapping of the surface of an object are described. The process involves establishing a radioactive wearing surface on the object through surface layer activation (SLA) and/or radioactive ion implantation (RII) and imaging the wearing surface with conformal photographic or x-ray film to produce a first autoradiograph providing a baseline profile of the wearing surface. After subjecting the object to wear during testing the wearing surface is again imaged with conformal photographic or x-ray film to produce a second autoradiograph providing a worn profile. The first and second autoradiographs of the wearing surface are digitized and compared to produce a differential wear map of the surface of the object.
