Abstract

To provide a space-saving bipolar plate for a fuel cell comprising an anode plate and a cathode plate, anode gas channels and cathode gas channels lead from main gas ports on opposite sides into an active area and are distributed across the width of said area such that they are subsequently diverted towards an opposite distribution area, and the coolant channels branch in the distribution area and, after branching, are diverted towards the anode gas channels and towards the cathode gas channels and, in each region of overlap with the anode gas channels and the cathode gas channels, are diverted collectively such that the coolant channels lead, together with the anode gas channels and the cathode gas channels, into the active area with no overlap and alternatingly with said anode gas channels and cathode gas channels.
