PURPOSE:To increase the mechanical strength of a solid electrolyte fuel cell and enhance the current efficiency thereof by disposing gas separator/ interconnectors of predetermined shape and current collecting corrugated plates between single cells and laminating a stack of cells thereby. CONSTITUTION:A plurality of single cells 1 have gas separator/interconnectors (abb. I/C)6 interposed between them and have terminal assemblies 7 disposed at upper and lower ends thereof and laminated to form a stack of cells. Each single cell 1 is square and a solid electrolyte film 2 has a pair of opposite sides which project by predetermined amount from the side of an oxygen electrode 3 and that of a fuel electrode 4, and make sealing contact with the bank face 10 of I/C6 to form a gas sealing surface. Each I/C6 has a current collecting face 9 which is caused to abut on the mountain or valley portion of the current collecting corrugated plate 5. The current collecting corrugated plate 5 has through-holes 8 which smooth circulation of actuating gas to assist in enhancing current efficiency of the stack. Each single cell is held by the I/C to increase the strength of the stack. |
