摘要： A fuel cell includes a membrane electrode assembly, a separator, a fluid channel, a fluid manifold, a plurality of protruding elastic members, and a plurality of sealing members. A fluid is to flow in a stacking direction through the fluid manifold. A connection channel is provided between the plurality of protruding elastic members to connect the fluid channel and the fluid manifold. The plurality of sealing members are provided adjacent to the plurality of protruding elastic members in the stacking direction and extend in a direction to cross a flow direction in which the fluid flows along the connection channel. Each of the plurality of protruding elastic members has overlapping regions that overlap the plurality of sealing members as seen from the stacking direction. The overlapping regions are separated from each other in the flow direction.

摘要： A fuel cell stack includes a stacked body, a first insulator, and a first shim. The stacked body includes electrolyte-electrode assemblies and separators. The electrolyte-electrode assemblies are stacked in a stacking direction and have a first end electrolyte-electrode assembly disposed at a first end of the stacked body. The separators includes a first end separator disposed at the first end of the stacked body between the first end electrolyte-electrode assembly and a first contact end plate having a first contact surface which the first end separator contacts. The first shim is provided in a first recess between the first contact end plate and the first insulator and has a thickness such that an outer peripheral surface of the first end separator is positioned between the first contact surface of the first contact end plate and an outer peripheral surface of the first insulator in the stacking direction.
