US Patent:

6383677, May 7, 2002

Filed:

Oct 7, 1999

Appl. No.:

09/413169

Inventors:

Jeffrey Peter Allen - Naugatuck CT

Assignee:

Allen Engineering Company, Inc. - Naugatuck CT

International Classification:

H01M 804

US Classification:

429 34, 429 12, 429 13, 429 36, 429 38, 429 39

Abstract:

A fuel cell is fitted with a current collector situated between a ribbed separator and an electrode. The current collector is comprised of a plurality of flat wires which span the peaks of the ribs of the separator. The flat wires are of sufficient thickness, width, and frequency to support the electrode against the compressive load of the fuel cell stack. The width and frequency are alterable to suppress or enhance reactant access to the electrode.

Appl. No.:

09/785594

Inventors:

Jeffrey P. Allen - Naugatuck CT

Assignee:

GenCell Corporation - Southbury CT

International Classification:

H01M 804

US Classification:

429 20, 429 17, 429 19, 429 31

Abstract:

An apparatus for auto thermal reforming hydrocarbon fuel in a fuel cell stack includes a plurality of fuel cells stacked together. Each fuel cell has an inlet manifold, and the inlet manifolds of the fuel cells are aligned with one another to form a manifold chamber. A porous wand extends through the manifold. A mixing device is positioned within the wand and is configured to carry fuel gas and oxidant through the wand.

Assignee:

GenCell Corporation - Southbury CT

International Classification:

H01M 802

US Classification:

429 37, 429 35

Abstract:

A fuel cell apparatus includes a fuel cell stack positioned within a housing. The housing is contained entirely within a compression assembly. In certain preferred embodiments, the fuel cell stack includes a plurality of bipolar separator plates formed of a plurality of segments, the compression assembly including mating pairs of anode compression bars and cathode compression bars secured to one another and being positioned between a pair of segments.

Appl. No.:

10/350863

Inventors:

Jeffrey Peter Allen - Naugatuck CT

Assignee:

GenCell Corporation - Southbury CT

International Classification:

B21D 2504

US Classification:

72302, 723796

Abstract:

A stretch-forming press for stamping continuously fed sheet metal includes a ram, a base member, and a feed mechanism configured to advance a strip of sheet metal through the stretch-forming press. A forming station has a die configured to form a desired pattern in the strip of sheet metal. A leveling station has a pair of opposed jaws slidably received in corresponding recesses of the stretch-forming press, with the jaws oriented at an angle with respect to a direction of travel for the strip of sheet metal as it passes through the leveling station.

International Classification:

H01M 802

US Classification:

429 34, 429 35, 429 36, 429 38, 429 39, 429 26

Abstract:

A fuel cell bipolar separator plate of variable length is formed from a sheet having a fixed width. The sheet is passed through a tool a predetermined distance and a pattern of ribs is formed on a central portion of the sheet with the tool to define a segment along the length of the sheet. The ribs define a fuel flow path on a first side of the sheet and an oxidant flow path on an opposed second side of the sheet. The sheet is passed through a tool a predetermined distance and the steps of forming the pattern on the sheet and passing the sheet through the tool are repeated until the sheet possesses a desired length, at which point the sheet is cut to a desired length.

US Classification:

429 46, 429 13, 429 34

Abstract:

The present invention provides an aqueous-based electrolyte slurry for molten carbonate fuel cells. The invention provides means to eliminate the potential for the preferential transport of potassium carbonate and subsequent irreversible alteration of the 62/38 molar ratio of the eutectic mixture of the lithium potassium carbonate electrolyte.
