    Abstract: A sub-assembly for an electrochemical stack, such as a PEM fuel cell stack, has a bipolar plate with sealing material extending from its upper face, around the edge of the bipolar plate, and onto its lower face. The bipolar plate is preferably a combination of an anode plate and a cathode plate defining an internal coolant flow field and bonded together by sealing material which also provides a seal around the coolant flow field. All of the sealing material in the sub-assembly may be one contiguous mass. To make the sub-assembly, anode and cathode plates are loaded into a mold. Liquid sealing material is injected into the mold and fills a gap between the edge of the plates, and portions of the outer faces of the plates, and the mold. In a stack, sub-assemblies are separated by MEAs which at least partially overlap the sealing material on their faces.

    Abstract translation: 用于电化学堆叠的子组件,例如PEM燃料电池堆,具有双极板,其具有从其上表面围绕双极板的边缘延伸到其下表面上的密封材料。 双极板优选地是限定内部冷却剂流场的阳极板和阴极板的组合,并且通过密封材料结合在一起,密封材料也围绕冷却剂流场提供密封。 子组件中的所有密封材料可以是一个连续的质量。 为了使子组件,将阳极和阴极板装载到模具中。 将液体密封材料注入模具中并填充板的边缘与板的外表面的部分和模具之间的间隙。 在堆叠中,子组件由MEA分开,MEA至少部分地与其表面上的密封材料重叠。

    Abstract: Some embodiments of the present invention provide a balance-of-plant system and apparatus suited for regulating the operation of an electrolyzer cell stack. Specifically, in some embodiments, a balance-of-plant system and apparatus is operable to regulate the respective pressures of at least two reaction products relative to one another. Various examples are provided to demonstrate how the respective pressures of two reaction products can be regulated in relation to one another in a pressure following configuration, thereby regulating the pressure differential across an electrolyte layer according to aspects of different embodiments of the invention. Some of the examples provided also include design simplifications and alternatives that may reduce production costs of electrochemical cells configured according to aspects of different embodiments of the invention.
