Abstract
A method for producing a bipolar plate (10) for a fuel cell (1), including a plate body (11) for separating the fuel cell (1) from a neighboring fuel cell (1) or a housing. The plate body (11) has a flow field structure (1b) for introducing the reactants into the fuel cell (1). The method includes the following steps: providing a mass (D1) made of electrically conductive particles and a polymer-based adhesive; applying the provided mass (D1) to the plate body (11) of the bipolar plate (10) in the form of the flow field structure (1b); pyrolising the applied mass (D1) which remains on the plate body (11) of the bipolar plate (10) as a shaping element in the form of the flow field structure (1b) and which is connected to the plate body.
