摘要： In a fuel cell stack and a method of producing the fuel cell stack, a first thickness of a first rubber seal member in a stacking direction before a tightening load is applied to a stack body is set such that, when the tightening load is applied to the stack body, a first amount of deformation of the first rubber seal member in the stacking direction is larger than a second amount of deformation of a top part of a first seal bead in the stacking direction.

摘要： A fuel cell stack includes a cell stack body and a terminal plate and an insulator disposed at an end of the cell stack body in a stacking direction. The cell stack body includes a plurality of stacked power generation cells. Each of the power generation cells includes a membrane electrode assembly and a separator. The terminal plate is disposed between the cell stack body and the insulator. Elastic structure which elastically presses the terminal plate toward the cell stack body is provided between the insulator and the terminal plate.

摘要： A resin frame equipped membrane electrode assembly includes an MEA having different sizes of components, and a resin frame member. A resin melt portion is provided for the resin frame member. The inside of a first gas diffusion layer is impregnated with resin as a part of the resin melt portion. A thin portion is provided at an outermost peripheral portion of the resin frame member through a step at an outermost peripheral portion of the resin melt portion, and the thin portion is thinner in a thickness direction than the resin melt portion.

摘要： A first outer peripheral seal in a first metal separator of a fuel cell stack includes a first peripheral metal bead. A first bypass stopper is provided in a space between a first end ridge and a first outer peripheral seal. The first bypass stopper prevents bypassing of an oxygen-containing gas by blocking part of the space. A gap is provided between the first bypass stopper and the first metal bead of a first outer peripheral seal. The gap separates the first bypass stopper from the first metal bead.

摘要： A first metal separator includes a seal bead protruding from a base plate. The seal bead includes a curved section having a curved shape in a plan view of the first metal separator. The combination of the radius of curvature and the angle of the curved section is set within a specific zone where variation in a seal surface pressure in a direction in which the seal bead extends is suppressed.

摘要： A tab of a load receiver forming a fuel cell separator member includes a base portion in the form of a metal plate, and a resin member covering the base portion. A hole, into which the resin member is partially inserted, is formed in the base portion. The resin member includes a thick portion, and a thin portion positioned closer to a first separator than the thick portion is. The hole is disposed so as to be overlapped with the thick portion.

摘要： A resin frame equipped membrane electrode assembly includes a membrane electrode assembly and a resin frame member around an outer peripheral portion of the membrane electrode assembly. An inner end of the resin frame member is joined to an electrolyte membrane. In the state before the inner end is joined to the electrolyte membrane, the inner end is narrowed inward in a manner that a surface of the inner end adjacent to the electrolyte membrane gets closer to a surface of the inner end opposite to the electrolyte membrane.

摘要： In a fuel cell separator member of a fuel cell stack, a first metal bead and first ribs are formed integrally with and protruded from a surface of the first metal separator. Each of the first ribs includes a first rib body and two first retracted portions. The protruding height of each of the two first retracted portions is smaller than the protruding height of the first rib body.

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 fuel cell stack includes a load receiver provided in a first separator, and a contact portion. The load receiver includes a protrusion protruding outward from an outer peripheral portion of the first separator. The protrusion includes a protrusion body positioned at the center in a width direction of the protrusion, and a pair of expansions expanded in the width direction from both ends of the protrusion body in the width direction. When the load receiver contacts the contact portion, only a top portion of the expansion contacts the contact portion.
