(DE19946695-A1)   NOVELTY - The fuel cell has a set of series arranged unit cells comprising of a negative and a positive electrode. Each cell includes a separator (2) that separates the negative electrode chamber of one unit cell from the positive electrode chamber of the next unit cell. The separator has at least one intermediate plating layer (70,71) on an aluminum based substrate (6) and a noble metal layer (72) layered on plating layer.    USE - Fuel cell separator construction for use in batteries with an aluminum based substrate.    ADVANTAGE - Producing the separator from zinc, copper or tin reduces the weight of the separator and using more than one plating reduces the ionization tendency from the aluminum based substrate.
