摘要： A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and/or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal. There is thus formed a “seal in place”, that is robust and can accommodate variations in tolerances and dimensions, and that can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be comparable with a wide variety of gases, liquid coolants and the like.

摘要翻译： 提供了用于形成用于燃料电池和其它电化学电池的复合和多重密封构造的密封技术。 为了提供用于氧化剂，燃料和/或冷却剂的密封室的密封件，提供了延伸穿过燃料电池组件的各种元件的凹槽网。 然后将密封材料源连接到外部填充口并注入凹槽网络中，然后将密封材料固化以形成密封。 因此，形成了“密封就位”，其是牢固的并且可以适应公差和尺寸的变化，并且可以在可能的情况下粘合到燃料电池组件的各个元件。 这避免了将许多单独的垫圈手动组装成复杂的槽形状的困难，劳动密集的成本和复杂性。 可以选择密封材料与各种各样的气体，液体冷却剂等相当。
