    • 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.

    • 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.
    • 在一个方面,燃料电池组件的第一(流场)板包括其上的第一流动通道。 流体通过延伸穿过第一板的开口传导到流动通道。 相邻的第二板协作提供用于歧管和开口之间的流动路径的表面。 另外的表面可以协作以提供流路和/或结构支撑。 第一板上的结构可能妨碍在包括第一流动通道的板面上的歧管板的流体连通。 所述地层可以在(例如,PEM型)燃料电池组件中提供结构支撑,和/或用于膜电极组件的夹紧和/或垫圈功能。 可以类似地提供第二流动路径用于(例如,反应物)流体的加湿。 第二流路可以包括流量调节器和/或计量孔。 第二板可以包括其上的第二流动通道。 第二板的流动路径可以被配置为为第一板的流动路径提供上述表面,而不会在每个板的流体服务之间产生干扰。 用于流体的歧管的乘法可以允许歧管省略对板的服务,其中不同的歧管可以服务于省略的板。

    • 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.
    • 一方面,燃料电池组件可以包括一个或多个(例如,PEM型)燃料电池。 用于燃料电池组件的流体服务可以包括诸如燃料和/或氧化剂的一些或多个反应物流体服务,以及加湿服务, 。 波轮可以位于用于流体歧管的任何入口和/或出口处。 这种脉动器可以用于沿着在燃料电池组件中延伸的流动路径的一部分引入压力变化。 在一个示例中,相对于燃料电池的阳极侧,压力变化可以用于从MEA的阳极侧清洗氮气覆盖层,因此可以提供包括氢的重整物用于电化学反应。 对于燃料电池的阴极侧,压力变化可以用于从MEA的阴极侧除去氮气和/或二氧化碳毯和产品流体,因此可以提供含氧的空气用于电化学反应 。 此外,可以除去多余的加湿流体。 可以获得更大的功率密度。 压力变化可以被配置为动态地变形MEA以辅助机械混合以促进流场燃料服务和/或增加功率密度。

    • 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.
