    • Provided is an SOFC stack having a stack structure which ensures the mechanical strength of the whole SOFCs without depending on the mechanical strength of each unit cell. The stack structure includes unit cells, separators, and seal portions. The unit cells are stacked. Each unit cell has a fuel electrode layer having a fuel electrode and an air electrode layer having an air electrode. The fuel electrodes of each unit cell are so disposed as to face each other across the sold electrolyte. The separators are disposed between the unit cells and separate the unit cells. The seal portions are provided in the fuel electrode layers and the air electrode layers, are equivalent to the separators or the solid electrolyte at least in the thermal expansion/contraction characteristic, and have nonporous parts integrated with the peripheries of the fuel electrode or the periphery of the air electrode and with the adjacent separator and solid electrolyte. A stream of fuel gas and a stream of air gas are supplied to the fuel electrode and the air electrode respectively.
    • 提供了具有堆叠结构的SOFC堆叠,其确保整个SOFC的机械强度而不依赖于每个单元电池的机械强度。 堆叠结构包括单元电池,分离器和密封部分。 单元电池堆叠。 每个单电池具有具有燃料电极的燃料电极层和具有空气电极的空气电极层。 每个单元电池的燃料电极被布置为在所销售的电解质上彼此面对。 分离器设置在单元电池之间并分离单元电池。 密封部设置在燃料电极层和空气电极层中,至少具有热膨胀/收缩特性等同于隔板或固体电解质,并且具有与燃料电极或周边的周边一体化的无孔部分 的空气电极和相邻的隔离物和固体电解质。 燃料气体和空气气流分别供应到燃料电极和空气电极。

    • A resin molding die (1) has a molding surface (6) formed of a low adhesion material (3) formed of a solid solution of La- Y 2 O 3 produced from Y 2 O 3 and an other oxide of La 2 O 3 . La 2 O 3 contains La, which has an ionic radius larger than Y 3+ , and is larger in basicity than Y 2 O 3 . The low adhesion material (3) contains La 2 O 3 at a predetermined ratio relative to a total of Y 2 O 3 and La 2 O 3 . The low adhesion material (3) thus has a large ionic radius contributing to a smaller number of sites per unit area than Y 2 O 3 , a larger basicity contributing to a smaller force binding the low adhesion material with a basic substance than Y 2 O 3 , and a ratio contributing to shape retention. The low adhesion material (3) thus less adhesive and more shape-retentive than Y 2 O 3 configures the molding surface (6). A low adhesion material that is less adhesive to a basic substance than Y 2 O 3 is and excellently shape-retentive, and an excellently releasable and shape-retentive resin molding die can thus be obtained.
    • 树脂成型模具(1)具有由由Y 2 O 3制成的La-Y 2 O 3的固溶体和La 2 O 3的其它氧化物形成的低粘合材料(3)形成的成型面(6) 。 La 2 O 3含有离子半径大于Y 3+的La,碱度大于Y 2 O 3。 低粘合性材料(3)相对于Y 2 O 3和La 2 O 3的总和以相对于预定比例含有La 2 O 3。 因此,低粘附性材料(3)具有大的离子半径,有助于每单位面积的位置数量少于Y 2 O 3,较大的碱度有助于将低粘附性材料与碱性物质结合的力小于Y 2 O 3,以及有助于形状保持的比例。 低粘合性材料(3)因此比Y 2 O 3更少的粘合剂和更多的形状 - 保持性构成了模制表面(6)。 与Y 2 O 3相比,对碱性物质的粘合性较差的粘合性低的材料具有良好的保形性,能够得到良好的脱模性和形状保持性的树脂成形模。
