Abstract
A fuel cell including a separator having a plurality of unit bodies continuously arranged along a first direction and arranged apart at predetermined intervals along a second direction orthogonal to the first direction, wherein each of the unit bodies has a wedge shape having a first inclined surface and a second inclined surface, connected at a predetermined angle at a vertex portion and two unit bodies adjacent along the second direction are arranged so that each vertex portion is not coaxially located with respect to a virtual line parallel to the second direction.
Claims18
A separator comprising a plurality of unit bodies continuously arranged along a first direction and arranged apart at predetermined intervals along a second direction orthogonal to the first direction,
- wherein each of the unit bodies has a wedge shape having a first inclined surface and a second inclined surface, connected at a predetermined angle at a vertex portion, and
- wherein two unit bodies adjacent along the second direction are arranged so that each vertex portion is not coaxially located with respect to a virtual line parallel to the second direction.
A fuel cell stack comprising:
- a membrane-electrode assembly;
- a gas diffusion layer provided on one side of the membrane-electrode assembly;
- and
- a separator disposed so that at least some regions of the separator are in contact with the gas diffusion layer,
- wherein said separator comprises a plurality of unit bodies continuously arranged along a first direction and arranged apart at predetermined intervals along a second direction orthogonal to the first direction,
- wherein each of the unit bodies has a wedge shape having a first inclined surface and a second inclined surface, connected at a predetermined angle at a vertex portion, and
- wherein two unit bodies adjacent along the second direction are arranged so that their respective vertex portions are not coaxially located with respect to a virtual line parallel to the second direction.
