US Patent:
6356433, Mar 12, 2002
Filed:
Aug 31, 2000
Appl. No.:
09/653621
Inventors:
Steven Z. Shi - Latham NY
John R. Davey - Los Alamos NM
Shimshon Gottesfeld - Los Alamos NM
Xiaoming Ren - Los Alamos NM
Assignee:
The Regents of the University of California - Los Alamos NM
International Classification:
H01G 900
US Classification:
361502, 361504
Abstract:
A sealed ultracapacitor assembly is formed with first and second electrodes of first and second conducting polymers electrodeposited on porous carbon paper substrates, where the first and second electrodes each define first and second exterior surfaces and first and second opposing surfaces. First and second current collector plates are bonded to the first and second exterior surfaces, respectively. A porous membrane separates the first and second opposing surfaces, with a liquid electrolyte impregnating the insulating membrane. A gasket formed of a thermoplastic material surrounds the first and second electrodes and seals between the first and second current collector plates for containing the liquid electrolyte.

Air Breathing Direct Methanol Fuel Cell

View page
US Patent:
6458479, Oct 1, 2002
Filed:
Nov 14, 2000
Appl. No.:
09/713149
Inventors:
Xiaoming Ren - Los Alamos NM
Shimshon Gottesfeld - Los Alamos NM
Assignee:
The Regents of the University of California - Los Alamos NM
International Classification:
H01M 810
US Classification:
429 33, 429 41, 429 42
Abstract:
An air breathing direct methanol fuel cell is provided with a membrane electrode assembly, a conductive anode assembly that is permeable to air and directly open to atmospheric air, and a conductive cathode assembly that is permeable to methanol and directly contacting a liquid methanol source. Water loss from the cell is minimized by making the conductive cathode assembly hydrophobic and the conductive anode assembly hydrophilic.

Methanol Sensor Operated In A Passive Mode

View page
US Patent:
6488837, Dec 3, 2002
Filed:
Dec 4, 2000
Appl. No.:
09/730142
Inventors:
Xiaoming Ren - Los Alamos NM
Shimshon Gottesfeld - Los Alamos NM
Assignee:
The Regents of the University of California - Los Alamos NM
International Classification:
G01N 27406
US Classification:
205787, 204421, 204422, 429 90
Abstract:
A sensor outputs a signal related to a concentration of methanol in an aqueous solution adjacent the sensor. A membrane electrode assembly (MEA) is included with an anode side and a cathode side. An anode current collector supports the anode side of the MEA and has a flow channel therethrough for flowing a stream of the aqueous solution and forms a physical barrier to control access of the methanol to the anode side of the MEA. A cathode current collector supports the cathode side of the MEA and is configured for air access to the cathode side of the MEA. A current sensor is connected to measure the current in a short circuit across the sensor electrodes to provide an output signal functionally related to the concentration of methanol in the aqueous solution.

Catalyst Inks And Method Of Application For Direct Methanol Fuel Cells

View page
US Patent:
6696382, Feb 24, 2004
Filed:
Nov 14, 2000
Appl. No.:
09/715211
Inventors:
Piotr Zelenay - Los Alamos NM
John Davey - Los Alamos NM
Xiaoming Ren - Los Alamos NM
Shimshon Gottesfeld - Los Alamos NM
Sharon C. Thomas - Vancouver, CA
Assignee:
The Regents of the University of California - Los Alamos CA
International Classification:
B01J 2100
US Classification:
502168, 502100, 429 40, 429 41, 429 42
Abstract:
Inks are formulated for forming anode and cathode catalyst layers and applied to anode and cathode sides of a membrane for a direct methanol fuel cell. The inks comprise a Pt catalyst for the cathode and a PtâRu catalyst for the anode, purified water in an amount 4 to 20 times that of the catalyst by weight, and a perfluorosulfonic acid ionomer in an amount effective to provide an ionomer content in the anode and cathode surfaces of 20% to 80% by volume. The inks are prepared in a two-step process while cooling and agitating the solutions. The final solution is placed in a cooler and continuously agitated while spraying the solution over the anode or cathode surface of the membrane as determined by the catalyst content.

Cold Start And Temperature Control Method And Apparatus For Fuel Cell System

View page
US Patent:
6821658, Nov 23, 2004
Filed:
Mar 2, 2001
Appl. No.:
09/798314
Inventors:
William P. Acker - Rexford NY
Shimshon Gottesfeld - Niskayuna NY
William W. Dailey - Loudonville NY
Assignee:
MTI MicroFuel Cells Inc. - Albany NY
International Classification:
H01M 800
US Classification:
429 13, 429 23, 429 24, 429 34
Abstract:
A fuel cell which provides improved performance during a cold start. Several embodiments are provided to enable the controlled introduction of fuel into the cathode of the fuel cell such that oxidation occurs, heat is released and the temperature of the fuel cell is raised. Such fuel may be introduced into the cathode directly or may be introduced into the anode and allowed to crossover an electrolytic membrane. Alternatively, the fuel may be directed through a special conduit which allows oxidation of some of the fuel as it flows through.

US Patent:
6824899, Nov 30, 2004
Filed:
Nov 9, 2001
Appl. No.:
10/040502
Inventors:
William P. Acker - Rexford NY
Michael S. Adler - Niskayuna NY
Shimshon Gottesfeld - Niskayuna NY
Assignee:
MTI MicroFuel Cells, Inc. - Albany NY
International Classification:
H01M 800
US Classification:
429 13, 429 22, 429 23
Abstract:
Apparatus and methods for regulating methanol concentration in a direct methanol fuel cell system without the need for a methanol concentration sensor. One or more operating characteristics of the fuel cell, such as the potential across the load, open circuit potential, potential at the anode proximate to the end of the fuel flow path or short circuit current of the fuel cell, are used to actively control the methanol concentration.

Modified Diffusion Layer For Use In A Fuel Cell System

View page
US Patent:
6890680, May 10, 2005
Filed:
Feb 19, 2002
Appl. No.:
10/078728
Inventors:
Gerhard Beckmann - Altamont NY, US
Xiaoming Ren - Guilderland NY, US
Paul F. Mutolo - Albany NY, US
Frank W. Kovacs - Waterford NY, US
Shimshon Gottesfeld - Niskayuna NY, US
Assignee:
MTI MicroFuel Cells Inc. - Albany NY
International Classification:
H01M004/96
H01M008/10
H01M004/88
US Classification:
429 44, 429 30, 429 33, 429 34, 429 42, 502101
Abstract:
A fuel cell diffusion layer providing a preferential path by which liquid reactants or byproducts may be supplied to or removed from a direct oxidation fuel cell is described. The modified diffusion layer will be typically on the cathode side of the fuel cell and its use is to eliminate or minimize flooding of the cathode diffusion layer area, which is a performance limiting condition in direct methanol fuel cells. In accordance with one embodiment of the invention, the diffusion layer includes a substrate that is coated with a microporous layer. A pattern may be embossed into the diffusion layer, to create preferential flow paths by which water will travel and thereby be removed from the cathode catalyst area. This avoids cathode flooding and avoids build up of potentially destructive pressure by possible cathodic water accumulation. This also provides a means for collecting cathode water for redirection In accordance with another aspect of the invention, the preferential path is established by applying a thicker microporous layer to the carbon cloth or carbon paper and drying it in such a fashion so that when it dries, the surface of the microporous layer cracks to provide the pathways.
