In solid polymer electrolyte fuel cells, a laminar flow of a dilute oxidant stream, for example air, may be disrupted by incorporating obstacles in the channels of an oxidant flow field. The laminar flow is changed to turbulent flow thereby enhancing the flow of oxygen to the membrane electrode assembly in the fuel cell and improving fuel cell performance.

En células de combustible sólidas del electrólito del polímero, un flujo laminar de una corriente diluída del oxidante, por ejemplo aire, puede ser interrumpido incorporando obstáculos en los canales de un campo del flujo del oxidante. El flujo laminar se cambia al flujo turbulento de tal modo que realza el flujo del oxígeno al montaje del electrodo de la membrana en la célula de combustible y que mejora funcionamiento de la célula de combustible.
