Abstract:
1. A structure for improving a laminating efficiency of a metal-separator for a fuel cell stack which includes: a unit cell having a membrane electrode assembly; a gas diffusion layer moving a reaction gas to the membrane electrode assembly; a metal-separator coupled to an outside of the gas diffusion layer so as to support the membrane electrode assembly; a gasket interposed between the membrane electrode assembly and the metal-separator so as to prevent the reaction gas from being leaked; and a connecting plate having a plurality of manifolds and coupled to an outside of the unit cell so as to support the unit cell, wherein the metal-separator comprises: an embossed structure that has a plurality of indentations and a plurality of projections alternately formed along at least one edge thereof so as to enable a plurality of the metal-separators to be stably laminated in a honeycomb shape.
