Further, the insulating portions 552 to 554 have a gas blocking property, and make it difficult for the fuel gas flowing through the gas flow path 2a to leak.
  • an oxide having low conductivity such as glass or mica can be used.
  • a specific material for example, amorphous glass or the like may be used, and in particular, crystallized glass or the like may be used.
  • the material of the insulating portions 541 to 544, 551 to 554 may be the same as, for example, the sealing materials 521 to 526, 531 to 536, or may be different.
  • the cells 1C according to the fourth embodiment are arranged in the first direction and electrically connected to the first element and the second element, and the metal member supporting the first element and the second element. Be prepared. Further, the cell 1C further includes a third element located at a distance from the first element with the gas flow path 2a through which the reaction gas flows flowing. Thereby, the durability of the cell 1C can be enhanced.
  • the first direction in which the first element and the second element are arranged intersects with the third direction in which the reaction gas such as fuel gas flows. Thereby, the durability of the cell 1C can be enhanced.
  • the fuel electrode faces the gas flow path 2a located inside the cell and the air electrode is located on the surface side of the cell, but the arrangement is opposite to this, that is, the air electrode is located. It can also be applied to a cell stack device facing the gas flow path 2a and having a fuel electrode located on the surface side of the cell.
  • the fuel cell, the fuel cell stack device, the fuel cell module, and the fuel cell device are shown as examples of the “cell”, the “cell stack device”, the “module”, and the “module accommodating device”.
  • Other examples may be an electrolytic cell, an electrolytic cell stacking device, an electrolytic module and an electrolytic device, respectively.
  • the cell 1 includes the first element and the second element (element portions 6a and 6b), and a metal member.
  • the first element and the second element are arranged in the first direction and are electrically connected.
  • the metal member has a support portion that supports the first element and the second element. Thereby, the durability of the cell 1 can be enhanced.
  • the cell stack device 10 has a cell stack 11 including a plurality of cells 1 described above. Thereby, the durability of the cell stack device 10 can be improved.
  • the module 100 includes the cell stack device 10 described above and a storage container 101 for accommodating the cell stack device 10. This makes it possible to increase the durability of the module 100.
  • the module accommodating device 110 includes the module 100 described above, an auxiliary machine for operating the module 100, and an outer case for accommodating the module 100 and the auxiliary equipment. Thereby, the durability of the module accommodating device 110 can be improved.
