APPARATUS AND METHOD FOR PRODUCING FUEL CELL SEPARATOR ASSEMBLY

[Problem] To provide an apparatus and method for manufacturing a fuel cell separator assembly whereby electrical resistance between cells can be satisfactorily suppressed. [Solution] The present invention is a method for manufacturing a fuel cell separator assembly (12), the manufacturing method having a joining step for bringing opposing projections of uneven portions of separators (13, 14) into contact with each other through use of pressing members (220) and joining the projections through use of a welding robot (250). In the joining step, an elastic member (230) is interposed so that a pressing force directed from a first separator side and/or a second separator side is imparted, and the opposing projections are brought into contact with each other by elastic deformation of the elastic member.
