摘要： A fuel cell separator member of a fuel cell stack includes a metal separator on which a seal bead is formed, and a pressure receiving member provided on a surface of the metal separator, separately from the metal separator. The pressure receiving member is provided along a seal bead, and the height of the pressure receiving member is lower than the height of the seal bead in the state where the tightening load is applied and no impact load is applied.

摘要： A method of manufacturing a plate with an insulating frame by using a metal mold. The plate includes an outer edge portion having a concavo-concave shape, and the metal mold includes a plurality of gate portions for injecting a molding material that forms the frame. The gate portions of the metal mold are at locations that correspond to the concave portions of the metal plate such that when the molding material is injected into the metal mold, an injection pressure of the molding material that can deform the metal plate will not deform the metal plate to an extent that deteriorates insulation resistance that is provided by the frame.

摘要： A fuel cell includes a membrane electrode assembly, a first metal separator, a second metal separator, linear protrusions, and embossed protrusions. The first metal separator is stacked on the membrane electrode assembly. The second metal separator is stacked on the first metal separator to define a coolant channel between the metal separators. The first metal separator includes wave-shaped protrusions projecting from the first metal separator by a first height to define to form the coolant channel. The linear protrusions are connected to both distal ends of each of the wave-shaped protrusions. The linear protrusions project from the first metal separator by a second height smaller than the first height. The embossed protrusions are connected to tip ends of the linear protrusions. The embossed protrusions project from the first metal separator by a third height larger than the second height to be in contact with the second metal separator.

摘要： A fuel cell is formed by sandwiching a membrane electrode assembly between a first separator and a second separator. An outlet connection channel connecting a fuel gas flow field with a fuel gas discharge passage is provided in the first separator. The outlet connection channel has a plurality of discharge holes extending through the first separator. The discharge holes are arranged in the direction of gravity. The discharge hole at the lowermost position has an opening elongated downward to have an opening area larger than opening areas of the other discharge holes above and adjacent to the discharge hole at the lowermost position.
