Abstract: In the present invention, when separation plates are stacked to be stored, adhesion between the gasket of a separation plate and a slip sheet can be remarkably reduced. Accordingly, the adhesion between a separation plate and a slip sheet is minimized when stacked separation plates are separated so that smooth workability can be ensured when a fuel cell stack is produced. The arrangement and long-term storability of a separation plate can be also stably ensured.
