A STRUCTURE TO IMPROVE LAMINATING EFFICIENCY OF A METAL-SEPARATOR FOR A FUEL CELL

摘要

A structure of a fuel cell stack is provided to improve the laminating property of a metal separator for a fuel cell by reducing the error in case of laminating process. A structure of a fuel cell stack comprises a membrane electrode assembly, a unit cell(100) comprising a gas diffusion layer, a metal separator(130) supporting the membrane electrode assembly, and a gasket(120); and an engagement plate comprising a manifold, wherein the metal separator comprises a plurality of separator manifolds formed in one end in length direction corresponding to the manifold, and an uneven structure comprising a projection and a groove formed along the circumference. The uneven structure is laminated in a shape of hive.
