摘要： A manufacturing method includes a cleaning step of irradiating by laser light a joining site of a first separator to which a second separator is to be joined, without joining the first separator and the second separator. In the cleaning step, at least a part of a joining site is irradiated by the laser light such that a plurality of irradiation marks created by the laser light make up a separated irradiation mark pattern in which the irradiation marks are disposed separated from each other.

摘要： A manufacturing method for manufacturing a fuel cell includes a laser application step and a bonding step. In the laser application step, a laser beam is applied to a carbon film of a separator including a metal plate and the carbon film covering a surface of the metal plate such that the metal plate is exposed by removing the carbon film within an application range of the laser beam. In the bonding step, the separator is bonded to a resin member within a range including at least part of a range where the metal plate is exposed.
