Beschreibung
Zusammenfassung:	The invention discloses a composite connecting pipe fitting between solid oxide fuel cell stacks. The pipe fitting sequentially comprises a metal section, a transition section, an insulating section,a transition section and a metal section in the gas output direction or the gas input direction. According to the composite connecting pipe fitting provided by the invention, the sealing surface is reduced, the sealing failure risk caused by thermal expansion and cold contraction is reduced, and meanwhile, the insulation problem between a gas circuit and the cell stacks and the stress absorption problem are solved. 本发明公开的一种固体氧化物燃料电池电堆间的复合连接管件，该管件在沿着输出气体方向或输入气体方向依次包括金属段、过渡段、绝缘段、过渡段和金属段。本发明提出的复合连接管件减少了密封面，降低了因热胀冷缩引起的密封失效风险，同时解决了气路与电堆间的绝缘问题，以及应力吸收问题。
