BIPOLAR PLATE WITH TWO-PASS ANODE

摘要

A fuel cell bipolar plate (1) includes first and second plates with ribs defining anode and cathode flow channels. The plates are nested so as to define a plurality of center flow channels (13). First and second edge areas are formed at ends of the plates. A plurality of first internal fuel manifolds (3) is formed in the first edge area and is in fluid communication with the center flow channels (13). A plurality of second internal fuel manifolds (4) is formed in the first edge area and is in fluid communication with the center flow channels and the anode flow channels (16). Aturnaround plenum (21) is formed in the second edge area (6) and is in fluid communication with the center flow channels (13) and the anode flow channels (16).
