Separator used for an electrochemical fuel cell comprises a conducting metal plate, a conducting coating membrane on the plate so that the separator contacts the electrode, and a stationary coating membrane

摘要

Separator (20) comprises a conducting metal plate (22), a conducting coating membrane (24) on the plate so that the separator contacts the electrode, and a stationary coating membrane (26) on the conducting plate so that the conducting membrane is not on the metal plate. An Independent claim is also included for a process for producing a separator comprising placing a conducting coating membrane on the conducting metal plate so that the separator contacts the electrode, and then applying the stationary coating membrane on the plate so that the conducting membrane is not on the plate. The stationary coating membrane has a stronger adhesion to the metal plate than the conducting coating membrane.
