METAL STRUCTURE PLATE FOR FUEL CELL

摘要

Disclosed is a metal structure plate in which filler is impregnated and that has flow channels. A bipolar plate is manufactured by the steps of: manufacturing a metal structure in a sponge type or a crosslinked type by processing metal material; increasing hardness and density of the metal structure by pressurizing the metal structure; impregnating filler into the metal structure through a brushing method or a rolling method or injection molding and drying the metal structure; and cutting or pressing the dried plate. The metal structure bipolar plate can satisfy various physical properties required in the bipolar plate by changing the composition of the filler to be impregnated.
