1. A bipolar plate for an electrochemical reactor, comprising at least one anode sheet and one cathode sheet, each having an internal face and an external face, the anode and cathode sheets being in contact with each other via their internal face, each anode and cathode sheet comprising, on its external face, channels for circulating reactive fluids, the channels demarcating, at the internal faces of the anode and cathode sheets, cooling pipes for a flow of a heat transfer fluid,
the channels of the anode and cathode sheets comprising alternating bosses and indentations,
the bosses of the anode sheet being arranged in a staggered manner and the bosses of the cathode sheet being arranged in a staggered manner, and
the bosses of the anode sheet being arranged in a staggered manner in relation to the bosses of the cathode sheet.
