    • An SOFC stack module including an integral individual stack manifold containing all of the gas pathways necessary for supply and exhaust of fuel gas and cathode air to and from the stack chimneys. The stack is mounted and hermetically joined directly to the manifold without an intermediate base plate. Flanges at the inlet and outlet ports couple to system distributary manifolds via high temperature sealing joints. The manifold preferably is fabricated of a ferritic stainless steel, and may be formed in a one-piece casting, a combination of multiple castings and stamped plates metallurgically joined (brazed or welded together), or stamped from sheet metal stock. Preferably, the manifold includes fin structures extending into adjacent fuel gas and cathode air chambers to enhance balancing of temperatures by heat exchange therebetween. Heat exchange may be further improved by configuring the manifold to have a plurality of interleaved anode and cathode gas supply chambers.
    • 一个SOFC堆叠模块,包括一个集成的单独的堆叠歧管,其包含供给和排出燃料气体和向烟囱排出阴极空气所需的所有气体通路。 堆叠被安装和气密地直接连接到歧管,而没有中间基板。 入口和出口处的法兰通过高温密封接头连接到系统分配歧管。 歧管优选地由铁素体不锈钢制成,并且可以以单件铸件形成,多个铸件和冶金接合(钎焊或焊接在一起)上的冲压板的组合,或者由金属板材冲压成型。 优选地,歧管包括延伸到相邻燃料气体和阴极空气室中的翅片结构,以通过其间的热交换来增强温度的平衡。 可以通过将歧管配置成具有多个交错的阳极和阴极气体供应室来进一步改善热交换。
