摘要： A separator for an electrochemical fuel cell provides a path for a fuel gas or an oxidative gas to an electrode and functions as a wall of a unit cell of the electrochemical fuel cell. The separator comprises a conductive metal plate, a conductive coating membrane, and a tight coating membrane. The conductive coating membrane coats the conductive metal plate where the separator contacts the electrode. The tight coating membrane coats the conductive metal plate where the conductive coating membrane does not coat the conductive metal plate. A conductivity of the conductive coating membrane is higher than the tight coating membrane, and the tight coating membrane has a tighter adhesion to the conductive metal plate than the conductive coating membrane. The conductive coating membrane comprises carbon, a precious metal, or an alloy of nickel and chromium. The tight coating membrane comprises a close-grained resin. In the electrochemical fuel cell including the separator, the electric resistance between the separator and the electrode can be restrained low, and a rust problem caused by coming-off of the conductive coating membrane from the conductive metal plate can be avoided with high reliability.
