In order to provide a bipolar plate for a fuel cell, providing an anode plate with an anode side and a coolant side, wherein a first structuring for forming an anode flow field is formed on the anode side, and a cathode plate with a cathode side and a coolant side, wherein a second structuring for forming a cathode flow field is formed on the cathode side; wherein structural elements, which are contacted by the coolant sides of the anode plate and the cathode plate, for forming a coolant flow field, are arranged between the anode plate and the cathode plate, which bipolar plate has an optimized pressure distribution in a fuel cell stack and increased stability in comparison with the prior art, it is proposed that the structural elements may be made of an elastic material and that the structural elements have a different height in different regions of the coolant flow field. A fuel cell stack and a vehicle are also disclosed.
A bipolar plate for a fuel cell, comprising:
A fuel cell system comprising a stack between two end plates, wherein the stack includes alternately arranged membrane electrode assemblies and bipolar plates, wherein each of the bipolar plates includes:
A vehicle comprising a fuel cell system comprising a fuel cell stack between two end plates, wherein the stack includes alternately arranged membrane electrode assemblies and bipolar plates, wherein each of the bipolar plates includes:
