    • Several members make up a joint in a high-temperature electrochemical device, wherein the various members perform different functions. The joint is useful for joining multiple cells (generally tubular modules) of an electrochemical device to produce a multi-cell segment-in-series stack for a solid oxide fuel cell, for instance. The joint includes sections that bond the joining members to each other; one or more seal sections that provide gas-tightness, and sections providing electrical connection and/or electrical insulation between the various joining members. A suitable joint configuration for an electrochemical device has a metal joint housing, a first porous electrode, a second porous electrode, separated from the first porous electrode by a solid electrolyte, and an insulating member disposed between the metal joint housing and the electrolyte and second electrode. One or more brazes structurally and electrically connects the first electrode to the metal joint housing and forms a gas tight seal between the first electrode and the second electrode.
    • 几个构件在高温电化学装置中构成接头,其中各种构件执行不同的功能。 该接头可用于连接电化学装置的多个电池(通常为管状模块),以产生例如用于固体氧化物燃料电池的多电池段串联堆叠。 接头包括将接合构件彼此接合的部分; 提供气密性的一个或多个密封部分,以及在各种连接部件之间提供电连接和/或电绝缘的部分。 用于电化学装置的合适的接头构造具有金属接头壳体,第一多孔电极,第二多孔电极,通过固体电解质与第一多孔电极分离,以及设置在金属接头壳体和电解质之间的绝缘构件,第二多孔电极 电极。 一个或多个钎焊结构地和电连接第一电极和金属接头壳体,并在第一电极和第二电极之间形成气密密封。
