1. A method for producing fuel cell separator assemblies comprising the steps of:

  • a) forming in thin sheet stock a plurality of different individual platelets with coordinate features selected from micro-channels, vias and manifolds, said features together forming at least one active area field for oxidant or fuel consumption in contact with a membrane electrode assembly;

    b) stacking said platelets with said individual platelet features in precise alignment with corresponding features of a matingly adjacent platelet to provide continuous circulation paths for said oxidant or fuel; and

    c) bonding said aligned platelets to form a monolithic separator having internal microchannels and access manifolds thereto.
