METHOD OF PRODUCING FUEL CELL-USE SEPARATOR AND DEVICE FOR PRODUCING IT

摘要

A method of producing a fuel cell-use separator comprising the abnormal layer removing step of removing an abnormal layer appearing in the front layer when a separator-use metal material is rolled, the conductor exposing step of allowing part of a conductor contained in the front layer portion of the metal material itself to project, and the passivating step of passivating the front layer portion of the metal material itself. Removing an abnormal layer in the abnormal layer removing step and removing the front layer portion of a metal material in the conductor exposing step can be done chemically and electrochemically by the same treatment, thereby reducing the number of treating steps, and improving the productivity and reducing the costs of a separator.
