摘要： A seal structure is disclosed for forming a substantially fluid tight seal between a UEA and a plate of a fuel cell system, the seal structure including a sealing member formed in one fuel cell plate, a seal support adapted to span feed area channels in an adjacent fuel cell plate, and a seal adapted to cooperate with a UEA disposed between the fuel cell plates, the sealing member, and the seal support to form a substantially fluid tight seal between the UEA and the one fuel cell plate. The seal structure militates against a leakage of fluids from the fuel cell system, facilitates the maintenance of a velocity of a reactant flow in the fuel cell system, and a cost thereof is minimized.

摘要： A PEM fuel cell includes a first plate having a flow field for directing a first fluid along a surface thereof. A second plate includes a flow field for directing a second fluid along a surface thereof. A seal is disposed between the first plate and the second plate. The seal includes a plate margin defining a header aperture for delivering the first fluid to the first plate. The seal defines a carrier having a first side supported by the flow field of the first plate whereby the first fluid is permitted to flow directly from the first header aperture to the flow field of the first plate. The carrier includes a gasket arranged on a second side. The gasket precludes the first fluid from flowing directly from the header aperture to the flow field of the second plate.

摘要： A MEA-frame assembly is arranged in a mold for injection molding to form a first flow passage arranged so as to extend along the outer periphery of an electrode between the outer periphery of the electrode and the inner periphery of a frame, a second flow passage arranged so as to extend along an inner elastic member between the inner periphery and outer periphery of the frame and a plurality of connecting flow passages which communicate the first flow passage with the second flow passage. An elastic resin is injected into the first flow passage to fill the first flow passage with the elastic resin and to fill the second flow passage with the elastic resin through each of the communicating flow passages, thereby an elastic member which hermetically seals the space between the MEA-frame assembly and the separator is integrally formed.

摘要： A gasket for a fuel cell, wherein the gasket includes the use of two or more different materials as the gasket. For example, ethylene propylene diene monomer (EPDM) and/or the like, or another more chemically inert gasket material, is located inside or on an inboard position and is the wetted material that is exposed to the fuel cell operating environment. Silicone and/or the like, or another potentially contaminating material with better cold temperature sealability, is located outside or on an outboard position and does not come in contact with the fuel cell internal environment. One method of constructing such a gasket would be two include two parallel bead traces of the gasket materials on a polyimide (e.g., KAPTON®) carrier, or the like.

摘要： The present invention provides a method of making a gasketed fuel cell membrane electrode assembly by simultaneously binding together the parts of the MEA, impregnating uncured elastomeric gasket material into the outer edge portions of each fluid transport layer, and substantially curing the uncured elastomeric gasket material so as to form anode-side and cathode-side gaskets. In order to form a raised-ridge microstructured contact pattern on the contact face of each gasket, patterning plates bearing a negative relief of a raised-ridge microstructured contact pattern may be positioned between the press platens and the uncured elastomeric gasket material.

摘要： A composite seal having a multilayer elastomeric construction and method for constructing the same is provided. More specifically, the present invention provides a composite seal comprised of a low-durometer elastomer compliant layer coated with, or alternatively encapsulated by, a thin protective layer for securely sealing a bipolar plate and a membrane electrode assembly of a fuel cell. The elastomer compliant layer is preferably a silicone constituent and the thin coat protective layer is preferably a fluoroelastomer or fluoropolymer constituent suitable for bonding to the elastomer compliant layer. The foregoing layers constructing the composite seal are preferably deposited directly onto the aforementioned fuel cell components along a predetermined periphery. The resulting composite seal is thin in construction, resistive to undesired chemical and thermal reactions and provides the necessary compressive compliance without undue stress on the fuel cell assembly.
