The metal bipolar plate for ultralight fuel cells is a metal plate composed of anode and cathode parts. The cathode part is made in the form of a corrugated metal plate with gas supply channels of rectangular cross section, through which the oxidizing agent/cooling agent is supplied. The anode part of the bipolar plate is flat. The surfaces of the anode and cathode parts of the bipolar plate are connected along the contour at the points of their contact. Fuel (hydrogen) is supplied through technological openings.
