FUEL CELL AND FLOW FIELD PLATE FOR THE SAME

A fuel cell comprising an anode electrode, a cathode electrode, and a polymer electrolyte membrane interposed therebetween; an anode flow field adjacent the anode electrode; and a cathode flow field adjacent the cathode; wherein the anode flow field comprises a single serpentine anode flow channel with at least one anode channel pass and at least one anode landing on a first surface, and the cathode flow field comprises at least one serpentine cathode flow channel with a plurality of cathode channel passes and cathode landings on a first surface, wherein each anode channel pass aligns and overlaps with an alternating cathode channel pass, and the pitch of the anode flow field is at least twice the pitch of the cathode flow field.
