PURPOSE:To reduce complexity of positioning cell parts and facilitate stack assembly by previously joining a separator plate, and a cathode. CONSTITUTION:The first joining member 12 is formed by stacking and joining a separator plate 21, a corrugated plate 22, a perforated current collecting plate 23, and a cathode plate 24. The separator plate 21 is formed by bending downward the faced side located in its A, A' sides to the extent equivalent to the thickness of the corrugated plate 22. The perforated current collecting plate 23 has rising parts in four corners which are fixed to L-shaped ends of bent parts of the separator plates 21. The second joining member 21 is formed by placing an anode 32 on a highly porous metal plate 31 for fuel gas flow, covering the ends located in B, B' sides with a covering plate 33, and joining them. These joining members are arranged so that the cathode 24 and the anode 32 are in contact with an electrolyte plate 11 and each gas flow passage is perpendicularly intersecting each other to constitute a fuel cell stack Y. |
