Beschreibung
Zusammenfassung:	A fuel cell has cell units and a manifold for uniformly supplying an anode fluid to each of the cell units. The manifold has a feed port through which an anode fluid is supplied, a first buffer section in fluid communication with the feed port for receiving the anode fluid and for reducing a flow rate of the anode fluid, a second buffer section in fluid communication with the first buffer section for receiving the anode fluid from the first buffer section at the reduced flow rate and for further reducing the flow rate of the anode fluid, and a block group formed of blocks spaced apart from one another to form flow channels in fluid communication with the second buffer section and through which the anode fluid at the further reduced flow rate flows. An array of fine openings is disposed in fluid communication with the cell units for receiving the anode fluid at the further reduced flow rate flowing through the flow channels so that the anode fluid is uniformly supplied to each of the cell units.
