Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01M 8/02
US Classification:
429 34, 429 38, 429 39
Abstract:
A bipolar plate for a fuel cell is provided that includes a flowfield having an active surface with an inlet region and an outlet region. The active surface of the flowfield is in communication with the inlet region and the outlet region and has at least one flow channel formed therein.

US Patent:
7749637, Jul 6, 2010
Filed:
Sep 19, 2005
Appl. No.:
11/229909
Inventors:
Jon P. Owejan - Honeoye NY, US
Chunxin Ji - Rochester NY, US
Thomas A. Trabold - Pittsford NY, US
Michael Cartwright - Naples NY, US
Steven G. Goebel - Victor NY, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01M 8/02
H01M 8/10
US Classification:
429 38, 429 30
Abstract:
A fuel cell including a water blocking layer positioned between anode gas flow channels and a gas diffusion media. The blocking layer prevents water from propagating through the gas diffusion media layer and entering the anode flow channels, while allowing gas from the flow channels to flow through the diffusion media layer to the membrane. A water accumulation channel can be provided around the perimeter of the gas diffusion media layer where blocked water is accumulated, and allowed to expand during cell freezing. A porous capillary wick can be provided in the accumulation channel for wicking water to the inlet end of the flow channels where it is used to humidify the anode gas coming into the fuel cell. The wick can have a tapered configuration so that it has a larger diameter at the gas input end of the flow channels.

Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01M 2/02
US Classification:
429414, 429457
Abstract:
A bipolar plate for a fuel cell is disclosed including a first unipolar plate having an active surface with a plurality of flowfield channels formed therein. The first unipolar plate further includes an inlet header disposed at a first end of the unipolar plate that is in communication with the active surface, and an outlet header disposed at a second end of the unipolar plate having an exhaust opening formed therethrough. A peripheral edge of the exhaust opening is chamfered and is also in communication with the active surface. The chamfered exhaust opening forms a water removal channel in the bipolar plate.

429450, 429414, 429457, 429483, 429480
Abstract:
A device and method to extract water from a moisture-rich fuel cell flowpath. A water transport unit is integrated into the fuel cell so that liquid water stagnation within flow channels and manifolds is reduced. In one embodiment, the device includes numerous flowpaths that include an active region and an inactive region. The water transport unit includes a hydrophilic member such that upon passage of a fluid with the excess water through the inactive region of the device flowpath and into the presence of the hydrophilic member, it absorbs excess water from the fluid.
