摘要： A fuel cell includes a membrane electrode assembly having a substantially rectangular shape having a first side and a second side opposite to the first side in a side direction. The substantially rectangular shape includes a first portion and a second portion. The first portion is closer to the first side than to the second side in the side direction. At least one of a cathode electrode and an anode electrode has a smaller amount of cracks in an electrode catalyst layer in the first portion than in the second portion. A fuel gas outlet manifold and an oxidant gas inlet manifold are closer to the first side than to the second side in the side direction. A fuel gas inlet manifold and an oxidant gas outlet manifold are closer to the second side than to the first side in the side direction.

摘要： A solid polymer electrolyte membrane is made from a solid polymer electrolyte membrane roll in which a solid polymer electrolyte membrane sheet is wound in a winding direction. A first electrode is disposed on a first surface of the solid polymer electrolyte membrane in a stacking direction. A second electrode is disposed on a second surface of the solid polymer electrolyte membrane in the stacking direction and has a size smaller than a size of the first electrode viewed in the stacking direction. A resin frame member has a rectangular peripheral shape and a rectangular window therein viewed in the stacking direction. The rectangular stepped membrane electrode assembly is provided in the rectangular window so that the outer peripheral surface of the solid polymer electrolyte membrane is surrounded by the resin frame member. The rectangular peripheral shape has a longitudinal side which extends in the winding direction.

摘要： A passage bead seal of a fuel cell joint separator includes a straight portion and curved portions. An oxygen-containing gas bridge section connecting the inside and the outside of a portion surrounded by a passage bead seal includes inner tunnels and outer tunnels coupled to an inner side wall and an outer side wall of a straight portion, and protruding in a separator thickness direction. The tunnel height is determined to be smaller than the bead seal height by not less than a predetermined value in a manner that a line pressure applied by a compression load to a front end surface of the straight portion becomes the same as a line pressure applied by the compression load to a front end surface of the curved 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： Each of separator members of a fuel cell stack includes a cell voltage terminal protruding outward from an outer peripheral portion of a separator body. Each of the cell voltage terminals includes a plate shaped terminal, first protrusions, and second protrusions. At least some of the cell voltage terminals are arranged in a line in a stacking direction. In the cell voltage terminals facing each other in the stacking direction, the first protrusion of one of the cell voltage terminals and the second protrusion of the other of the cell voltage terminals face each other, and contact each other through an electrically insulating member.

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.
