A flow field plate for use in a fuel cell includes a non-porous plate body having a flow field that extends between first and second ends of the non-porous plate body. The flow field includes a plurality of channels having channel inlets and channel outlets, a fluid inlet portion that diverges from the first end to the channel inlets, and a fluid outlet portion that converges from the channel outlets to the second end. A fuel cell including the flow field plate includes an electrode assembly having an electrolyte between an anode catalyst and a cathode catalyst. The flow field of the flow field plate is side by side with the electrode assembly. A method of processing a flow field plate includes forming the flow field in a non-porous plate body.
