Abstract
A fuel cell stack is provided in which a plurality of single cells each including a membrane electrode assembly are stacked in a stacking direction. The fuel cell stack includes a plurality of electrical insulation members each connected to an outer peripheral portion of a corresponding one of the membrane electrode assemblies. The fuel cell stack further includes a first displacement absorbing member disposed between each insulation member and an adjacent insulation member.
Claims18
A fuel cell stack in which a plurality of single cells each including a membrane electrode assembly are stacked in a stacking direction, the fuel cell stack comprising:
- a plurality of insulation members each connected to an outer peripheral portion of a corresponding one of the membrane electrode assemblies, the plurality of insulation members being electrically insulating;
- and
- a first displacement absorbing member disposed between each insulation member and an adjacent insulation member.
A fuel cell stack in which a plurality of single cells are stacked in a stacking direction, the fuel cell comprising:
- a plurality of membrane electrode assemblies each including an electrolyte membrane;
- and
- outer peripheral members configured and arranged to absorb displacement between the plurality of membrane electrode assemblies, each of the outer peripheral members being connected to an outer peripheral portion of a corresponding one of the plurality of membrane electrode assemblies.
A fuel cell stack comprising:
- a plurality of membrane electrode assemblies;
- and
- displacement absorbing means for absorbing displacements between each of the membrane electrode assembly and an adjacent membrane electrode assembly, and for supporting the plurality of membrane electrode assemblies at outer peripheral portions thereof.
