摘要：
A solid oxide fuel cell stack in which first and second cell plates are alternately stacked. The first cell plates comprises a substrate having a plurality of opening portions, a groove which extends through the plurality of opening portions formed on a lower surface of the substrate, a solid electrolyte layer which covers the opening portion formed on an upper surface of the substrate, a fuel electrode layer which covers the opening portions formed on the solid electrolyte layer, and an air electrode layer formed on the lower surface of the substrate so as to extend along the opening portions and the groove. The second cell plates has a structure in which the air electrode layer is replaced with the fuel electrode layer in the first cell plate. In this fuel cell stack, the air electrode layer of the first cell plate faces the air electrode layer of the second cell plate, and the fuel electrode layer of the first cell plate faces the fuel electrode layer of the second cell plate. A method of manufacturing the solid oxide fuel cell stack comprises preparing the first cell plate, preparing the second cell plate, alternately stacking the first and second cell plates, and collectively sintering the stacked first and second cell plates.
摘要（中）：
固体氧化物燃料电池堆，其中第一和第二电池板交替堆叠。 第一单元板包括具有多个开口部分的基板，延伸穿过形成在基板的下表面上的多个开口部分的凹槽，覆盖形成在基板的上表面上的开口部分的固体电解质层 覆盖形成在固体电解质层上的开口部的燃料电极层和形成在基板的下表面上的空气电极层，以沿着开口部和槽延伸。 第二单元板具有其中空气电极层被第一单元板中的燃料极层替代的结构。 在该燃料电池堆中，第一电池板的空气极层与第二电池板的空气极层相对，第一电池板的燃料极层与第二电池板的燃料电极层相对。 制造固体氧化物型燃料电池堆的方法包括：准备第一电池板，制备第二电池板，交替堆叠第一电池板和第二电池板，并共同烧结层叠的第一和第二电池板。
