摘要： A spring loaded direct oxidation fuel cell assembly reduces the effects of precompression relaxation. A near flat spring and a distribution plate form a spring assembly that is disposed between a membrane electrode assembly and one of the current collectors in the fuel cell. The components are assembled into a fuel cell assembly and are precompressed, and a spring yielding process is performed. While precompression is being applied, a set of pins and a plastic frame are insert molded around the fuel cell assembly to hold the components in place. Subsequently, as the precompression relaxes, the spring assembly forces act to maintain an evenly distributed compression on the MEA, thereby compensating for the loss of precompression. A related method of manufacturing a fuel cell assembly is provided.

摘要： A fluid flow plate is preferably formed with conductive member(s) and non-conductive material(s). The conductive member(s) and/or the non-conductive material(s) form portion(s) of land(s) and/or flow channel(s) on face(s) of the plate. The flow channel(s) pass between and/or among the land(s). The flow channel(s) can be optimized to service fluid(s) for a fuel cell assembly. The conductive member(s) form electrical path(s) between, among, about and/or around position(s) on the face(s) of the plate. The electrical path(s) serve to conduct electrical current generated by the fuel cell assembly. The non-conductive material(s) can form brace(s) for, and/or seal(s) with, portion(s) of the flow channel(s). The non-conductive material(s) can form portion(s) of a periphery of the face(s) of the plate, and/or portion(s) of any appropriate geometric feature(s) for the plate. The non-conductive material(s) can be injection-molded. The non-conductive material(s) can form means for aligning the fluid flow plate with an adjacent plate. The non-conductive material(s) can form means for maintaining clamping pressure on a component between the fluid flow plate and an adjacent plate.

摘要： In one aspect, a fuel cell assembly may include one or more (e.g., PEM-type) fuel cell(s). Fluid(s) service(s) for the fuel cell assembly may include reactant fluid(s) service(s) such as service(s) of fuel(s) and/or oxidant(s), along with humidification service(s). A pulsator may be positioned at any entrance and/or exit for the fluid manifolds. Such pulsator(s) may serve to introduce pressure variation(s) along part(s) of flow path(s) extending in the fuel cell assembly. In one example, with respect to an anode side of a fuel cell, the pressure variation(s) may serve to purge a nitrogen blanket from the anode side of the MEA so reformate including hydrogen may be supplied for electrochemical reaction. With respect to a cathode side of the fuel cell, the pressure variation(s) may serve to remove a nitrogen and/or carbon dioxide blanket and product fluid from the cathode side of the MEA so air containing oxygen may be supplied for the electrochemical reaction. Also, excess humidification fluid may be removed. A greater power density may be obtained. Pressure variation(s) may be configured to dynamically inflect the MEA to assist mechanical mixing(s) in promoting flow field fuel service(s) and/or increasing power density.

摘要： A fuel cell system having internal pushback of water, with a compact, thermally integrated enthalpy exchanger enabling effective hydration control in a small fuel cell system is provided. The enthalpy exchanger provides for the moisture in the fuel cell effluent to be used to humidify the incoming air stream to allow the fuel cell to be operated at higher temperatures while avoiding dry out. The enthalpy exchanger includes a moisture permeable membrane which collects moisture from the exhaust flow and makes this moisture available to an incoming air stream, thus humidifying the incoming air stream. In addition, the waste heat from the fuel cell reactions is transferred to the incoming air stream. The exhaust stream from the anode can also be used to provide additional moisture and heat to the enthalpy exchanger to be added to the incoming air stream. A water separator is also provided in one embodiment.

摘要： A heat switch system includes a first surface thermally coupled to at least a portion of an associated component requiring temperature control. A second surface is spaced by a gap relative to the first surface. A gas generator is coupled to a first chamber configured to hold a gas generated by the gas generator. The first chamber includes a diaphragm configured to be deformed in response to an increase in an amount of the gas in the first chamber. A deformation of the chamber in response to the increase in the amount of the gas in the first chamber causes movement of the first surface and/or the second surface such that the first surface and the second surface move toward each other to reduce the gap and heat is transferred from the first surface to the second surface.

摘要： A wide-area electrostatically-actuated shutter is provided that includes a thin, flexible, diaphragm that is placed between two rigid electrode structures. In one embodiment of the invention, the diaphragm has a set of openings in it. These openings overlap with corresponding openings in one of the rigid electrodes such that when the diaphragm is contiguous to that electrode, the openings provide apertures through which vaporous fuel can flow. The opposite electrode does not have overlapping openings, thus it forms a seal that prevents gas or vapor from passing through it when the diaphragm is in contact with the opposite electrode. The shutter is actuated electrostatically by an associated driver that applies a voltage to the diaphragm such that when the high voltage is applied to the diaphragm, the diaphragm is attracted to the fixed electrode that is tied to ground. Alternatively, when is desired to place the shutter in the opposite position, the diaphragm is placed at ground, which, in turn, pulls it towards the fixed electrode that is at a high voltage, to adjust the shutter. The shutter can be rapidly opened and closed at a high frequency in a PWM mode or a PFM mode.
摘要翻译： 提供了一种广域静电致动的快门，其包括薄的，柔性的隔膜，其被放置在两个刚性电极结构之间。 在本发明的一个实施例中，隔膜在其中具有一组开口。 这些开口与其中一个刚性电极中的相应开口重叠，使得当隔膜与该电极邻接时，开口提供空气燃料可以流过的孔。 相对的电极没有重叠的开口，因此当隔膜与相对电极接触时，它形成一个防止气体或蒸汽通过它的密封件。 通过向隔膜施加电压的相关联的驱动器静电地驱动快门，使得当高压施加到隔膜时，隔膜被吸引到被接地的固定电极。 或者，当希望将快门放置在相反的位置时，隔膜被放置在地面上，接着将其拉向朝向高电压的固定电极，以调节快门。 在PWM模式或PFM模式下，快门可以高频快速打开和关闭。

摘要： A fluid flow plate for a fuel cell includes a first face and a fluid manifold opening for receiving a fluid and at least one flow channel defined within the first face for distributing a reactant in the fuel cell. A dive through hole is defined in and extends through the fluid flow plate. The dive through hole is fluidly connected to the fluid manifold opening by an inlet channel, defined within an opposite face of the plate. The dive through hole and the inlet channel facilitate transmission of a portion of the fluid to the flow channel. A groove, adapted to receive a sealing member, is also defined within the first face and/or the opposite face. The sealing member may comprise a gasket which seals the respective fluid manifolds, thereby preventing leaking of fluid.

摘要： In one aspect, a first (flow field) plate of a fuel cell assembly includes a first flow channel(s) thereon. Fluid is conducted to the flow channel through an opening extending through the first plate. An adjacent second plate cooperates in providing surface(s) for a flow path between a manifold and the opening. Additional surface(s) may cooperate in providing the flow path and/or structural support therefor. A formation on the first plate may impede fluid communication from the manifold plate on a plate face including the first flow channel. The formation may provide structural support in a (e.g., PEM-type) fuel cell assembly, and/or a clamping and/or gasketing function for a membrane electrode assembly. A second flow path may similarly be provided for humidification of the (e.g., reactant) fluid. The second flow path may include flow regulator(s) and/or metering orifice(s). The second plate may include a second flow channel thereon. Flow path(s) for the second plate may be configured to provide the aforementioned surface(s) for the flow path(s) for the first plate without interference among fluid service for each plate. A multiplication of manifolds for a fluid may allow a manifold to omit service for a plate, where a different manifold may service the omitted plate.

摘要： A heat spreader assembly that provides electrical, thermal and structural functions to the fuel cell. The heat spreader assembly comprises two bulk composite material layers, and a heat spreader element. The heat spreader element includes a copper layer sandwiched between two stainless steel layers. The stainless steel layers are bonded to the bulk composite layers by a conductive thermal set adhesive. The lamination applied to the stainless steel layers enables heat and electricity to flow from the cathode while maintaining low resistance among other layers of the fuel cell. The copper layer diffuses heat across the layer and functions as cathode current collector for a fuel cell. The bulk composite material layers function as a cold side of an enthalpy exchanger system and a cathode flow field. Further the composite material includes flow channels formed throughout the material to evenly distribute incoming air over the enthalpy exchanger membrane and to the cathode of the MEA.
