Patent ID: 8497048

Claim:
A fuel cell separator having an airtight gasket, characterized in that a gasket is integrally formed with both surfaces of a separator in a closed curve, the gasket including a first gasket and a second gasket, and the separator including a first separator and a second separator wherein the first gasket is provided on the first separator and includes; a side line integrally formed on inner and outer surfaces of the first separator along the four corners thereof; a first 1-main line formed on the outer surface of the first separator and extending through a space between the inner sides of a hydrogen manifold and hydrogen transport holes to a region adjacent to the inner sides of a coolant manifold and an air manifold placed on the same line as the hydrogen manifold along the width direction; a first 2-main line formed on the inner surface of the first separator and extending through a space between the hydrogen transport holes and a coolant flow field to a region adjacent to the inner side of the air manifold placed on the same line along the width direction; and a plurality of first coolant guide lines formed on the inner surface of the first separator and arranged between the coolant manifold and the coolant flow field along the longitudinal direction, and wherein a portion of a first 1′-sub-lines extending from the first 1-main line and a first 2-sub-lines extending from the first 2-main line are integrally connected to each other on the inner sides of the hydrogen and air manifolds by a first connection line, and the rest of the first 1′-sub-lines extending from the first 1-main line and the first coolant guide lines are integrally connected to each other on the inner side of the coolant manifold by a second connection line.
