Abstract
Fuel is provided to an inlet (14) of a cascade region (15) which has a plurality of stages (17-23), each of which divides fuel flow evenly into a pair of corresponding slots (24-26). The flow is then spread across a floor surface (41) of a cascade exit header (40), the flow spreading into areas between the slots. The flow is then directed into an open cavity which is in fluid communication with the inlets of the fuel flow fields (12) of the fuel cells, reaching the fuel flow field inlets uniformly and simultaneously.
