ABSTRACT:
A unitized plate such as a bipolar plate for a fuel cell assembly is provided. The unitized plate includes a plurality of active regions electrically insulated from one another, and a plurality of inlet and outlet apertures formed in the plate. Each of the active regions is in fluid communication with a dedicated inlet aperture adapted to selectively deliver gaseous reactants thereto. A fuel cell assembly having a plurality of independently operable fuel cell stack units, and a method for operating the fuel cell assembly, is also provided.
