The present invention relates to a manufacturing method of a multi-cell separation plate for a fuel cell. The present invention comprises: a step of molding a multi-cell separation plate body; a step of compressing photosensitive dry films on upper and lower sides of the multi-cell separation plate body; a step of connecting first mask films on upper and lower sides of the photosensitive dry films; a step of molding flow passages and insulating lines on the upper and lower sides of the multi-cell separation plate body by carrying out an exposure phenomenon on the first mask films; a step of molding bridge grooves on the insulating lines, which are molded as the upper and lower sides of the multi-cell separation plate body, by drilling; a step of connecting second mask films on the flow passages of the multi-cell separation plate body having the bridge grooves, and coating a conductive material; and a step of gaining the multi-cell separation plate having a conductive bridge where the conductive material is inserted into the bridge grooves while removing the second mask films and coating the conductive material on the upper and lower sides. 본 발명은 연료전지용 멀티셀 분리판 제조방법에 관한 것이다. 이를 위하여, 본 발명은 멀티셀 분리판 몸체를 성형하는 단계; 상기 멀티셀 분리판 몸체의 상하면에 감광성 드라이 필름을 압착하는 단계와; 상기 감광성 드라이 필름의 상하면에 1차 마스크 필름을 접합하는 단계와; 상기 1차 마스크 필름에 노광과 현상을 수행하여 상기 멀티셀 분리판 몸체의 상하면에 유로와 절연라인을 성형하는 단계와; 상기 멀티셀 분리판 몸체의 상하면으로 성형된 절연라인에 드릴링으로 브릿지홀을 성형하는 단계와; 상기 브릿지홀이 형성된 멀티셀 분리판 몸체의 유로에 2차 마스크 필름을 접합한 후 전도성 소재를 코팅하는 단계; 및 상기 2차 마스크 필름을 제거하여 상하면에 전도성 소재가 코팅되며 브릿지홀에 전도성 소재가 주입된 전도성 브릿지가 구비된 멀티셀 분리판을 얻는 단계가 포함됨을 특징으로 한다.
