Production of a bipolar plate for collecting electrodes and distributing between fuel cells comprises creating an electrically conducting fuel cell component and applying a graphite-containing/conducting carbon layer on one side

摘要

Production of a bipolar plate (10) comprises creating an electrically conducting fuel cell component (100) with a first side and applying a graphite-containing/conducting carbon layer on the first side (6) of the fuel cell component by sputtering a graphite target using an unsymmetrical magnetron field with a closed field. An independent claim is also included for a product comprising a fuel cell cell-bipolar plate.
