The present invention relates to a manufacturing method of a separation plate for a fuel cell, a separation plate for a fuel cell manufactured thereby, and a fuel cell including the separation plate. The present invention applies a multi-stage injection method and shapes two or more separation plates into one separation plate in order to realize a multicell, thereby reducing a stack volume by reducing the size of the separation plate to increase stack output density. According to an embodiment of the present invention, the manufacturing method of a separation plate for a fuel cell comprises: a first step of forming electrical conduction portions on both sides of a dividing portion after installing the dividing portion inside an injection mold; a second step of forming a passage for connecting two among manifolds to the electrical conduction portions after forming the manifolds separated from each other on the electrical conduction portions; and a third step of being in contact with at least one manifold of the manifolds in a space where the dividing portion is removed after removing the dividing portion inside the injection mold, and forming an insulating portion arranged between the electrical conduction portions. |
