Abstract
A fuel cell includes a separator plate including manifold holes formed in opposite sides thereof, a plurality of flow-path lands protruding between the manifold holes, a plurality of flow-path channels between the flow-path lands, and a plurality of communication holes formed between ends of the flow-path channels and the manifold holes, and a gasket coupled to the separator plate, and a plurality of separating portions protruding from the blocking portion into gaps between the neighboring communication holes so as to separate the communication holes from one another, wherein ends of the flow-path lands that do not face the separating portions extend toward the communication holes farther than do ends of the flow-path lands that face the separating portions.

A fuel cell including:
- a plurality of separator plates laminated;
- a plurality of membrane electrode assembly mounted between two adjacent separator plates;
- and
- a plurality of gaskets mounted between two the adjacent separator plates,
- wherein the plurality of separator plates each include manifold holes disposed in opposite sides thereof, a plurality of flow-path lands protruding between the manifold holes, a plurality of flow-path channels between the flow-path lands, and a plurality of communication holes disposed between ends of the flow-path channels and the manifold holes so as to be spaced apart from one another by a given distance;
- wherein the plurality of gaskets coupled to the plurality of separator plates, the plurality of gaskets each include a blocking portion located between the manifold holes and the communication holes so as to block a gap between the manifold holes and the communication holes, and a plurality of separating portions protruding from the blocking portion into gaps between the neighboring communication holes so as to separate the communication holes from one another, and
- wherein ends of the flow-path lands that do not face the separating portions extend toward the communication holes farther than do ends of the flow-path lands that face the separating portions.
