Abstract:
1. A membrane electrochemical generator, comprising: a multiplicity of reaction cells, wherein each of said reaction cells comprises a metallic reticulated current collector, an active area, and is delimited by two bipolar sheets, each of said bipolar sheets comprises a metallic central body having a dimension larger than the active area of the reaction cells and a frame made of a polymeric material, said frame comprises: a first feed opening and a second feed opening for the passage of gaseous reactants, at least one of the first and the second feed openings also provides a passage for cooling water to enter the reaction cell, a first discharge opening and a second discharge opening for discharging reaction products, at least one of the first and the second discharge openings also provides a passage for cooling water to exit the reaction cell, a multiplicity of channels each having two ends, wherein one end opens to the active area of the reaction cell while the other end opens at one of the first feed opening, the second feed opening, the first discharge opening, and the second discharge opening.
