摘要:
A fuel cell stack includes a box-shaped casing and a stack body in the box-shaped casing. The stack body is formed by stacking a plurality of unit cells. The casing includes end plates, a plurality of side plates, angle members, and coupling pins. The angle members couple adjacent ends of the side plates. The coupling pins couple the end plates and the side plates.

摘要:
A first metal separator of one of adjacent power generation cells and a second metal separator of the other of the adjacent power generation cells are directly stacked together to form a coolant flow field. The first metal separator has a press line protruding toward the coolant flow field, between a fuel gas flow field and an inlet buffer. The second metal separator has a press line protruding toward the coolant flow field, between an oxygen-containing gas flow field and an inlet buffer. The press lines contact each other to limit flow of the coolant into a back surface buffer.

摘要:
A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.

摘要:
A first metal separator of a fuel cell comprises a metal plate, and a first seal member is formed integrally on both surfaces of an outer edge of the metal plate. A first rib having a frame shape is provided around an oxygen-containing gas supply passage or the like of the metal plate. The first rib has a rib surface spaced away from an inner end surface of the metal plate around the oxygen-containing gas supply passage or the like, toward the oxygen-containing gas supply passage or the like.

摘要:
A first separator to which a resin film is joined beforehand is set in a cavity formed between a lower die and an upper die of an injection molding machine. At the time of die locking by moving the upper die toward the lower die, in the case where the total thickness of the resin film and the first separator is larger than a predetermined dimension, the resin film is pressed by the lower die or the upper die, and thus, the resin film is deformed by compression within its elastic deformation range.
摘要:
A press separator made of a stainless steel sheet, for providing excellent corrosion resistance and electric conductivity by a combination of a passive coating and a deposition of boride or boron carbide, restriction corrosion without separation or coming-off, by press forming, of depositions, and ensuring an extended service. A stainless steel sheet, containing 0.005-1.5 wt. %, of B and having deposited on the surface thereof at least one kind out of M23 (C, B)6 type boron carbide, and M2B type and MB type borides, is press-formed in a corrugated shape having continuous irregularities, with angles of bent portions formed by bending or unbending by press forming being set at at least 15 degrees and an outward bending R-value at up to 1 mm.
