The invention relates to a method for producing a bipolar plate () for a fuel cell (), comprising a plate body () for separating the fuel cell () from a neighbouring fuel cell () or a housing, wherein the plate body () has a flow field structure () for introducing the reactants into the fuel cell (). To that end, according to the invention, the method comprises 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 said plate body.
