Patent ID: 8123889

Claim:
An adhesion method of separators, comprising the steps of: molding a first separator and a second separator by compressing a mixture of carbon and thermosetting resin at a molding temperature, stacking the second separator, which becomes an opposite separator, to the first separator on a surface of the first separator, on which an adhesive is coated, thereby obtaining a separator unit as a set; and stacking two or more of the separator units on one another, and curing the adhesive; wherein a curing temperature when the adhesive is cured is equal to or more than the molding temperature of the separators, wherein the adhesive is selected as a low temperature thermosetting adhesive in response to a material and curing temperature of the separators, wherein a surface pressure at which the adhesive is cured is equal to or more than a surface pressure applied when separator units, which are prepared and uncured, are stacked on one another for a dimensional measurement/adjustment of a stacked thickness of the separator units.
