Appl. No.:

09/454020

Inventors:

Robin J. Guthrie - East Hartford CT
Thomas J. Corrigan - Coventry CT
Stanley P. Bonk - Tolland CT

Assignee:

International Fuel Cells, LLC - South Windsor CT

International Classification:

H01M 200

US Classification:

429 34, 429 38, 429 17

Abstract:

An integrated manifold system for a fuel cell power plant includes a first fuel cell stack and a second fuel cell stack, wherein a common manifold is adapted to be in fluid communication with the first fuel cell stack and the second fuel cell stack. The common manifold includes a first plenum for diverting a first reactant to each of the first and second fuel cell stacks, and a second plenum for accepting the first reactant as the first reactant is exhausted from each of the first and second fuel cell stacks.

International Classification:

H01M 202

US Classification:

429 34, 429 12, 429 13, 429 30, 429 38

Abstract:

A fuel cell power plant includes a first cell stack assembly having a plurality of planar fuel cells in electrical communication with one another and a second cell stack assembly having a plurality of planar fuel cells in electrical communication with one another. An inter-stack manifold assembly is disposed between the first and second cell stack assemblies and provides an electrical pathway between the first and second cell stack assemblies. A baffle is formed internally to the manifold assembly for feeding a substantially uniform proportion of a reactant stream to the first and second cell stack assemblies while collecting an exhausted reactant stream from the first and second cell stack assemblies.

H01M008/06

US Classification:

429 38, 429 13, 429 39, 138 39, 138 42

Abstract:

Fuel is provided to an inlet () of a cascade region () which has a plurality of stages (), each of which divides fuel flow evenly into a pair of corresponding slots (). The flow is then spread across a floor surface () of a cascade exit header (), the flow spreading into areas between the slots. The flow is then directed into an open cavity which is in fluid communication with the inlets of the fuel flow fields () of the fuel cells, reaching the fuel flow field inlets uniformly and simultaneously.

International Classification:

H01M 8/06
H01M 8/04

US Classification:

429415, 429512, 429428

Abstract:

An inlet fuel distributor (-) has a permeable baffle () between a fuel supply pipe () and a fuel inlet manifold () causing fuel to be uniformly distributed along the length of the fuel inlet manifold. A surface () may cause impinging fuel to turn and flow substantially omnidirectionally improving its uniformity. Recycle fuel may be provided () into the flow downstream of the fuel inlet distributor. During startup, fuel or inert gas within the inlet fuel distributor and the fuel inlet manifold may be vented through an exhaust valve () in response to a controller () so as to present a uniform fuel front to the inlets of the fuel flow fields ().

Inventors:

Robin J. Guthrie - East Hartford CT, US

International Classification:

H01M 8/04
H01M 8/24

US Classification:

429444, 429452

Abstract:

A fuel cell assembly () has a plurality of fuel cell component elements () extending between a pair of end plates () to form a stack (), and plural reactant gas manifolds () mounted externally of and surrounding the stack, in mutual, close sealing relationship to prevent leakage of reactant gas in the manifolds to the environment external to the manifolds. The reactant gas manifolds are configured and positioned to maximize sealing contact with smooth surfaces of the stack and the manifolds. One embodiment is configured for an oxidant reactant manifold () to overlie the region where the fuel reactant manifold () engages the stack. Another embodiment further subdivides an oxidant reactant manifold to include a liquid flow channel (), which liquid flow channel overlies the region where the fuel reactant manifold () engages the stack.

US Classification:

429434, 429512, 429454

Abstract:

An example energy dissipation device for controlling a fuel cell fluid includes a conduit extending in longitudinal direction between a first opening and a second opening. A flow control insert is configured to be received within the conduit. The flow control insert is configured to cause a fuel cell fluid to flow helically relative to the longitudinal direction.
