    Abstract: A fuel cell and a method for producing the same are provided. The fuel cell includes a membrane electrode assembly and a gas diffusion layer that is disposed at each of opposite surfaces of the membrane electrode assembly, and includes a plurality of compressed parts that are formed by pressure at positions spaced out at predetermined intervals on the gas diffusion layer. The fuel cell further includes a separator that is in contact with an outer surface of the gas diffusion layer, and has a plurality of land parts that protrude toward the gas diffusion layer, and a plurality of channel parts that form flow paths between the land parts. The land parts respectively protrude toward the compressed parts of the gas diffusion layer to come in contact with the compressed parts.

    Abstract: The present invention provides a fuel cell separator with a gasket manufactured by integrally forming a gasket on one side of a separator; independently injection molding a frame gasket on a frame such that a first airtight portion covers the entire surface of the frame to maintain the shape of the frame gasket and a second airtight portion projects upward and downward from both ends of the first airtight portion; and bringing the first airtight portion of the frame gasket into contact with the other side of the separator with the gasket formed on one side thereof. To create a fuel cell stack in certain embodiments, the invention stacks the second airtight portion of the frame gasket on another second airtight portion of an adjacent unit cell with a membrane-electrode assembly interposed therebetween.
