Abstract
The bipolar separator is formed by the superimposition of two distribution plates and two cooling plates, the two cooling plates being arranged between the two distribution plates, each distribution plate having an outer face and an inner face, the outer face of each distribution plate being provided with distribution channels for the flow of a reactive fluid, the cooling plates defining internal conduits for the circulation of a cooling fluid.
Claims18
A bipolar separator for an electrochemical reactor, the bipolar separator comprising:
- two distribution plates each having an outer face and inner face, the outer face of each of the two distribution plates being provided with a distribution area in which distribution channels for flow of a reactive fluid extend along a longitudinal direction of the respective distribution plate, an entire area of the inner face of each of the respective distribution plates that is opposite the distribution area of the respective distribution plate being substantially flat;
- and
- two cooling plates disposed between the two distribution plates, the two cooling plates defining internal conduits for circulation of a cooling fluid between the two cooling plates, each of the two cooling plates having a first face facing an adjacent one of the two distribution plates and a second face facing another of the two cooling plates, at least one of the two cooling plates having, on the first face, at least one sealing groove configured to receive a seal interposed between the cooling plate and the adjacent distribution plate.
