A separator and a production method therefore which are excellent in processability and corrosion resistance, and can reduce the number of members of a fuel cell and shorten a production process. The separator (1) comprises a separation unit (13) for separating the flow paths of hydrogen gas and oxygen gas, and a seal unit provided at the outer peripheral portion, for preventing the leakage of hydrogen gas and oxygen gas, the separation unit (13) and the seal unit (14) being formed integrally by plastic deforming, for example, by press working a metal thin sheet. A coating layer (31) is formed on the metal thin sheet (30) to coat the surface of the metal thin sheet (30), and an ac power produced at the interface between polymer film (20) and a catalyst electrode (21) on contact of the coating layer (31) with the catalyst electrode (21) is picked up as an ac current and is collected at a collecting plate after passing through the separator (1). Further, a polymer elastic layer (40) is provided at the part contacting the polymer film (20) of the seal protrusion of the seal unit (14), and the polymer elastic layer (40) contacts the polymer film (20) to seal. |
