Abstract
A method of manufacturing a separator assembly for fuel cell includes a separator assembly forming step in which a separator assembly including a first metal separator and a second metal separator each having a protruding bead portion is formed by joining together the surfaces of the first and second metal separators opposite from their respective bead portions protruding, and a preload applying step in which a pair of platens apply a preload in a thickness direction of the separator assembly to a bead seal section formed of one pair of the bead portions, and thereby the bead seal section is plastically deformed. In the preload applying step, the preload applied to a linear portion of the bead seal section is set to be smaller than the preload applied to a curve portion of the bead seal section.
