Abstract
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.
