Patent ID: 8062805

Claim:
A membrane electrochemical generator comprising: a multiplicity of reaction cells and a multiplicity of cooling cells, wherein each of said cooling cells is interposed between two reaction cells, each of said reaction cells comprises a metallic reticulated current collector, an active area, and is delimited by two bipolar sheets, each of said cooling cells comprises a reticulated conductive element 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, a first discharge opening and a second discharge opening for discharging reaction products, an opening for feeding a coolant into a cooling cell, and 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.
