Water Electrolysis System

View page
US Patent:
6375812, Apr 23, 2002
Filed:
Mar 13, 2000
Appl. No.:
09/524250
Inventors:
Andrei Leonida - West Hartford CT
Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
C25B 900
US Classification:
204269, 204270, 2042751
Abstract:
A water electrolysis system includes a water electrolysis cell stack having an anode and a cathode. A water storage tank having an outlet is disposed above the cell stack and communicates with an inlet of one of the anode and the cathode of the cell stack for gravity feeding water from the water storage tank to the cell stack. A phase separator is disposed below and in communication with the water storage tank. The phase separator has an inlet for receiving a two phase stream including water and product gas exiting an outlet of the one of the anode and cathode of the cell stack, and includes a conduit having a lower end disposed within the phase separator for receiving water recovered in the phase separator. The conduit has an upper end extending into the water storage tank. Further, the conduit defines a plurality of openings along a portion of the conduit disposed in the phase separator such that the product gas received in the inlet of the phase separator enters the inside of the conduit through the openings and entrains and lifts water upwardly therewith through the conduit and into the water storage tank whereby water is recirculated through the cell stack.

Electrolyte Support Member For High Differential Pressure Electrochemical Cell

US Patent:
7217472, May 15, 2007
Filed:
Dec 18, 2003
Appl. No.:
10/739650
Inventors:
Andrei Leonida - West Hartford CT, US
Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
H01M 2/14
US Classification:
429 38, 429 34, 429 39, 429 44, 204279, 204283, 204284, 29557, 29558, 264469, 264470, 264482
Abstract:
A support member is useful for supporting membranes such as solid polymer electrolyte ion exchange membranes such as those used in electrochemical cell applications. The support member has a first lattice pattern on a first side of a single piece of material. A second lattice pattern on a second side of the single piece of material cooperates with the first lattice pattern to establish a plurality of flow passages across the material. Each lattice pattern has a corresponding plurality of recesses that extend partway through the material and overlapping portions of the recesses define the flow passages. In a disclosed example, the monolithic support member lattice patterns are established using chemical etching.

US Classification:
429418, 429405, 429416, 429422
Abstract:
A fuel cell system comprising a first electrode-electrolyte assembly having a first electrode coupled to one side of thereof and a second electrode coupled to a generally opposite side of the first electrode-electrolyte assembly, and a first conduit for delivering fuel to the first electrode at ambient temperature. The fuel cell system includes a second electrode-electrolyte assembly having a third electrode coupled thereto assembly, and a fourth electrode coupled to a generally opposite side of the second electrode-electrolyte assembly; and a mesh positioned between and in sealing engagement with the second electrode and the third electrode. A second conduit is in fluid communication with the fourth electrode for delivering oxidant thereto. The fuel cell system further includes means for providing an electrical potential across the first electrode-electrolyte assembly and an electrical load circuit for using an energy output generated across the second electrode-electrolyte assembly.

View page
US Patent:
7935456, May 3, 2011
Filed:
Sep 6, 2006
Appl. No.:
11/517112
Inventors:
Andrei Leonida - West Hartford CT, US
International Classification:
H01M 8/04
H01M 8/24
H01M 2/40
H01M 2/38
US Classification:
429514, 429457
Abstract:
A fluid conduit for use in an electrochemical cell, the fluid conduit comprising a support comprising an elastically deformable material and having a plurality of apertures extending therethrough defining a mesh through which fluid communication can be maintained and a peripheral sealing area; a flow plate positioned adjacent the support, the flow plate including an inlet and an outlet; and a separator positioned adjacent the support. The support, flow plate, and separator are sealingly engaged with one another and cooperate to define a plurality of flow paths in fluid communication with and extending axially between the inlet and the outlet. The support, flow plate, and separator can be comprised of a metallic material coated with an electrically conductive joining compound for providing sealing engagement and electrically conductive communication therebetween.

US Patent:
7955751, Jun 7, 2011
Filed:
Mar 31, 2004
Appl. No.:
10/814019
Inventors:
Andrei Leonida - West Hartford CT, US
Robert J. Roy - West Springfield MA, US
Kurt Matthew Critz - Enfield CT, US
Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
H01M 8/02
H01M 2/08
US Classification:
429510, 429508, 429509
Abstract:
An electrochemical cell has an anode cavity and a cathode cavity. The anode cavity and the cathode cavity sandwich an electrochemically conductive medium. The anode cavity and/or the cathode cavity have electrically conductive plates assembled using a solid bonding material. Each plate has nesting volumes and protrusions provided in the perimeter seal area. The protrusions of one plate fit into the volumes of an adjacent plate to eliminate the offset introduced by the bonding material thickness.
