Abstract:
A fuel cell includes a membrane electrode assembly having an anode side and a cathode side, a first gas diffusion layer adjacent the cathode side of the membrane electrode assembly, and a first flow field plate contacting the first gas diffusion layer. The first flow field plate includes a reactant inlet, a reactant outlet, and a plurality of flow field chambers separated from one another by at least one rib. The reactant inlet is separated from the plurality of flow field chambers by at least one rib and the reactant outlet is separated from the plurality of flow field chambers by at least one rib. The ribs are configured to force a reactant flowing from the reactant inlet to the reactant outlet to enter the first gas diffusion layer at least twice.
