Abstract
A fuel cell is disclosed. The fuel cell includes a cell stack including a plurality of unit cells stacked in a first direction, an enclosure surrounding side portions of the cell stack and including at least one opening to expose at least one of opposite end portions of the cell stack therethrough, first and second end plates respectively disposed at the opposite end portions of the cell stack, and a gasket disposed between a target end plate disposed in the at least one opening in the enclosure, among the first and second end plates, and the enclosure in order to seal the cell stack.
Claims20
A fuel cell, comprising:
- a cell stack comprising a plurality of unit cells stacked in a first direction;
- an enclosure surrounding side portions of the cell stack, the enclosure comprising at least one opening to expose at least one of opposite end portions of the cell stack therethrough;
- first and second end plates respectively disposed at the opposite end portions of the cell stack;
- a gasket disposed between a target end plate disposed in the at least one opening in the enclosure, among the first and second end plates, and the enclosure, the gasket being configured to seal the cell stack, wherein the target end plate comprises a body that comprises an inner surface that faces the cell stack and an outer surface that is opposite the inner surface, wherein the gasket is disposed between the body and the enclosure;
- and
- a partition wall disposed so as to face at least a portion of the outer surface of the body in the first direction, the body and the partition wall sealing the cell stack together with the enclosure using the gasket, wherein the gasket is disposed between the partition wall and the enclosure;
- wherein the outer surface of the body comprises a non-manifold region in which no manifold is disposed and a manifold region in which a manifold is disposed, the non-manifold region being coupled to the partition wall and the manifold region being not coupled to the partition wall;
- wherein a portion of the gasket is disposed between the body and the enclosure in the manifold region;
- and
- wherein the other portion of the gasket is disposed between the partition wall and the enclosure in the non-manifold region.
