Abstract
The invention relates to a fuel cell having a membrane electrode arrangement (16) arranged between two separator plate units (44), a first fluid area (12) for distribution of a first fluid which is adjacent to one side of the membrane-electrode arrangement (16), a second fluid area (14) for distribution of a second fluid which is adjacent to a side of the membrane-electrode arrangement (16) opposite this side, with a separating wall (36) being arranged in at least one fluid area (12) and subdividing the fluid area (12) into at least one metering area (32) and one fluid subarea (34), with the at least one metering area (32) having a fluid connection to the adjacent fluid subarea (34) at at least one metering point (38), such that the first fluid can be metered from the metering area (32) through the metering point (38) into the adjacent fluid subarea (34). According to the invention, starting from an input point (24), at the edge, for the first fluid into the fluid area (12), a cross section of the fluid subarea (34) increases in the flow direction (40) of the first fluid towards an output port (26).
