摘要： A fuel cell joint separator includes a passage bead and an outer bead. In a dual seal section where the passage bead and the outer bead extend next to each other, a ridge protruding from one surface of a metal separator is formed integrally with the metal separator, between the passage bead and the outer bead. The height of the ridge is smaller than the height of the bead seal compressed by the tightening load. A joining line is provided between the outer bead and the ridge.

摘要： A power generating cell is equipped with an MEA to which a resin frame is attached, and a first metal separator. In the first metal separator, there are provided an oxygen-containing gas flow field through which an oxygen-containing gas flows along an electrode surface, an outer peripheral bead surrounding the oxygen-containing gas flow field and which prevents leakage of a reaction gas, and a plurality of first bypass stopping convex portions that prevent bypassing of the reaction gas. Intermediate convex portions that support the resin film are provided between mutually adjacent ones of the first bypass stopping convex portions.

摘要： A power generation cell includes a frame member. The frame member includes a first frame shaped sheet and a second frame shaped sheet that are joined together. The second frame shaped sheet is provided outside a cathode through a gap. A method of operating a fuel cell includes supplying a first reactant gas to a channel formed between the frame member and a first separator, a pressure of the first reactant gas being higher than a pressure of a second reactant gas, and supplying the second reactant gas to a channel formed between the frame member and a second separator.

摘要： A power generation cell or a fuel cell includes an MEA, a first separator, and a second separator. A frame member is provided on an outer peripheral portion of the MEA. The frame member includes a frame member inner peripheral portion and a frame member outer peripheral portion held between the first separator and the second separator. The central position of a power generation area of the MEA in the thickness direction and the central position of the frame member outer peripheral portion in the thickness direction are offset from each other. Further, a first seal line of the first separator and a second seal line of the second separator, sealing the frame member outer peripheral portion, are non-symmetrical with each other.

摘要： A power generation cell (fuel cell) includes a membrane electrode assembly and first and second metallic separators arranged respectively on opposite sides of the membrane electrode assembly. An oxygen containing gas supply passage, a communication passage bead section (bead seal) that surrounds the oxygen containing gas supply passage, and a bridge section are disposed on the first metallic separator. At a location where the bridge section is disposed, the width of a root section of the communication passage bead section is greater than the width of the root section of the communication passage bead section at other locations thereof.
