Claim 14:
15. A fuel cell comprising a plurality of fuel cell units, with each fuel cell unit of the plurality of fuel cell units comprising:
a) a support structure having a plurality of flow channels; and
b) an active layer membrane coupled with the support structure, the active layer membrane comprising at least one electrode layer,
wherein each flow channel of the plurality of flow channels is configured to direct one of air and fuel across at least one electrode layer of an active layer membrane to create electric current; and
wherein each flow channel of the plurality of flow channels includes at least one enhancement feature formed in and extending from a surface of the flow channel that is configured to disrupt a formation of a boundary layer near a surface of the active layer membrane where reactions occur, wherein (i) a first group of flow channels of the plurality of flow channels that direct a flow of air is located on one side of the support structure and (ii) a second group of flow channels of the plurality of flow channels that direct a flow of fuel is located on an opposite side of the support structure, and wherein the first group of flow channels is arranged in a zig-zag configuration with the second group of flow channels.
