1. A method for producing bipolar plates for fuel cells, the method comprising:
providing a substrate strip in a coil, the substrate strip being pre-coated with a reactive coating and/or catalyst coating;
cutting a first substrate plate from the pre-coated substrate strip;
cutting a second substrate plate from the pre-coated substrate strip;
forming or stamping structures into the first substrate plate to form an anode plate;
forming or stamping structures into the second substrate plate to form a cathode plate; and
joining the anode plate to the cathode plate to form a bipolar plate.
