<P>PROBLEM TO BE SOLVED: To provide a gas supply pipe jointing structure not affected by the thickness of a separator. <P>SOLUTION: A stack is formed by alternately laminating a plurality of power generation cells 5 arranging electrode layers on both sides of a solid electrolyte layer and plate-shaped separators each having a gas flow passage therein. Tabs 13, 17 to which gas flow passages are connected are extended at outer peripheral parts of the respective separators 8, and connection members 14, 18 are welded on the tabs 13, 17. Passage holes 15, 19 communicated with the gas flow passages, to which gas supply pipes 10, 9 are connected from a side are arranged in the connection members 14, 18. The stack is formed by arranging the separators 8 so that the connection members 14, 18 adjacent to each other in a lamination direction are shifted in a zigzag form. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
