(WO9607211-A1)      The fluid manifold assembly comprises a fluid impermeable housing, a device within the housing for introducing at least one inlet fluid stream to each of the fuel cell stacks, and a device within the housing for exhausting at least one outlet fluid stream from each of the fuel cell stacks. The introducing device comprises at least one inlet passage formed within the housing, each of the at least one inlet passage containing one of the at least one inlet fluid stream within the housing.    The exhausting device comprises at least one outlet passage formed within the housing, each of the at least one outlet passage containing one of the at least one outlet fluid stream within the housing. The at least one inlet fluid stream comprises an inlet fuel stream and an inlet oxidant stream. The introducing device comprises two inlet passages, each containing one of the inlet fuel stream and the inlet oxidant stream. The at least one outlet fluid stream comprises an outlet fuel stream and an outlet oxidant stream. The exhausting device comprises two outlet passages, each containing one of the outlet fuel stream and the outlet oxidant stream.    ADVANTAGE -   Improves volumetric efficiency of array. Reduced complexity.
