A unit cell of a fuel cell includes: an insert including a membrane electrode assembly and a gas diffusion layer; a foamed body disposed on an outer side surface of the insert; and a frame covering an outer side surface of the foamed body such that a polymer resin is injected to the outer side surface of the foamed body while the polymer resin partly penetrates into the foamed body.

Unit cell of fuel cell and method of manufacturing the same

A frame gasket may include a flat base, which is positioned along the edge of stack constitutional parts and which includes a first elastic base and reinforced fibers mixed therein to ensure sealing of a fuel cell stack, and first projection units, which project over the base and which include a second elastic base.

Frame gasket for fuel cell and method of molding the same

A fuel cell separator includes a first separator plate and a second separator plate for an anode or a cathode. The first and second separator plates are adjacent to each other for assembly in a fuel cell stack. A first protrusion is formed at an edge portion of the first separator plate and protrudes toward the second separator plate arranged facing the first separator plate. A second protrusion is formed at an edge portion of the second separator plate and protrudes toward the first separator plate arranged facing the second separator plate. With the first and second separator plates adjacent to each other, since side surfaces of the first and second protrusions push each other, assembly positions of the first and second separator plates are regulated. The first and second protrusions are arranged such that opposing side surfaces thereof are spaced from each other. A third gasket is arranged in a gap between the first and second protrusions.

A fuel cell separator includes a first separator plate and a second separator plate for an anode or a cathode. The first separator plate and the second separator plate are adjacent to each other for assembly in a fuel cell stack. The fuel cell separator further includes a first protrusion formed at an edge portion of the first separator plate and protruding toward the second separator plate arranged facing the first separator plate and a second protrusion formed at an edge portion of the second separator plate and protruding toward the first separator plate arranged facing the second separator plate. With the first separator plate and the second separator plate adjacent to each other, since opposing side surfaces of the first protrusion and the second protrusion push each other, assembly positions of the first separator plate and the second separator plate are regulated.
