Abstract
A method for producing a bipolar plate () for a fuel cell (), including a plate body () for separating the fuel cell () from a neighboring fuel cell () or a housing. The plate body () has a flow field structure () for introducing the reactants into the fuel cell (). The method includes the following steps: providing a mass (D) made of electrically conductive particles and a polymer-based adhesive; applying the provided mass (D) to the plate body () of the bipolar plate () in the form of the flow field structure (); pyrolising the applied mass (D) which remains on the plate body () of the bipolar plate () as a shaping element in the form of the flow field structure () and which is connected to the plate body.
