Summary: | The invention relates to a bipolar plate (3) for a fuel cell arrangement (1), in particular for placement between two adjacent membrane electrode arrangements, comprising at least one or two plates disposed plane-parallel relative to one another, wherein a flow field (F) is formed from the channel structures made in the respective plate at least on one or both outer sides, respectively, said channel structures comprising a plurality of channels (K) running between a fluid inlet (E) and a fluid outlet (A) and webs (S) running between two channels (K). According to the invention, the channels (K) and/or the webs (S) comprise at least one varying channel width (b1), one varying web width (b2) and/or one varying channel distance (a) on at least one of the outer sides along a flow direction (R) of a fluid between the fluid inlet (E) and the fluid outlet (A). |
