SOLID ELECTROLYTE FUEL CELL AND STACK STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a solid-electrolyte fuel cell and stack structure with enhanced rigidity and suppressed occurrences of stress concentration.

SOLUTION: The solid electrolyte fuel cell is configured with simplex cells 4; a circular thin-sheet metallic separator 2 having a gas introducing port 21 and gas discharging ports 22 in the central portion, and cell mounting parts 25 for the simplex cells 4 to be fixed thereto, another circular thin-sheet metallic separator 3 having a gas introducing port 31 and gas discharging ports 32 in the central portion and flow channel members 5 accommodated in a bag S formed between the two separators 2 and 3 for communication of their channels with the gas introducing ports 21, 31 and the gas discharging ports 22 and 32 of the two separators 2 and 3 to effect gas supply and gas discharge inside the bag S and either flow channel joined member 5, within the bag portion S to at least one of the either separator 2 or 3 of the two separators 2 and 3.
