摘要:
A plate for a fuel cell is disclosed, wherein an inlet aperture is disposed at a first end of the plate and an outlet aperture is disposed at a second end of the plate. The plate includes a first side and a second side. The first side of the plate has a flow field formed therein between the inlet aperture and the outlet aperture, the flow field having a plurality of flow channels formed therein, the plurality of flow channels in communication with a plurality of outlet ports formed in the plate. The second side of the plate has a plurality of drainage channels formed therein adjacent the outlet aperture, the plurality of drainage channels in fluid communication with the outlet ports and the outlet aperture, wherein a cross-sectional area occupied by each of the plurality of flow channels is substantially equal to a cross-sectional area occupied by each of the plurality of drainage channels.
