US Patent:

8551667, Oct 8, 2013
Filed:

Apr 17, 2008
Appl. No.:

12/105071
Inventors:

Larry J. Markoski - Raleigh NC, US
Dilip Natarajan - Cary NC, US
Alex Primak - Morrisville NC, US
Assignee:

INI Power Systems, Inc. - Morrisville NC
International Classification:

H01M 8/04
H01M 8/08
US Classification:

429450, 429428
Abstract:

A fuel cell includes an anode including an anode catalyst, a cathode, a channel that is contiguous with the anode, and a liquid electrolyte in the channel. The cathode includes a gas diffusion electrode, a cathode catalyst on the gas diffusion electrode, and a hydrogel on the cathode catalyst. The hydrogel is between the anode and the cathode, and includes an aqueous liquid and a polymer. The polymer has an acid capacity less than 0. 8 meq/g and/or has no sulfonic acid groups covalently bound to the polymer. A method of generating electricity includes flowing a liquid electrolyte through the channel, oxidizing a fuel at the anode, and reducing a gaseous oxidant at the cathode.

US Patent:

20050202305, Sep 15, 2005
Filed:

Feb 24, 2005
Appl. No.:

11/067463
Inventors:

Larry Markoski - Raleigh NC, US
Dilip Natarajan - Cary NC, US
Alex Primak - Cary NC, US
International Classification:

H01B001/24
H01M008/02
H01M004/88
H01M004/86
US Classification:

429038000, 252511000, 429030000, 429044000, 502101000
Abstract:

A fuel cell is described. The fuel cell includes current collectors, each of which includes a substrate of lightweight material, such as Kapton material. Micro channels are formed via laser machining or chemical etching into the substrate. The current collectors further include conductive layers sputtered on the substrate, and protective coating on the conductive layers. A variety of materials are available for the conductive layers. The fuel cell so developed is particularly well suited to mobile applications, such as electronic devices.
