A membrane electrochemical generator comprises a multiplicity of reaction cells (101) mutually connected in series and assembled according to a filter-press type configuration. Each reaction cell is delimited by a pair of conductive bipolar plates (103), which comprises a multiplicity of first calibrated holes (113a) for the passage of the gaseous reactants and a multiplicity of second calibrated holes (113b) for the discharge of the reaction products and of the optional residual reactants. The cooling cells (102) comprises a rigid peripheral portion (102a), whereupon a gasket (117) is laid, defining and sealing on each face of such peripheral portion a zone of collection of the gaseous reactants (118a) and a zone of collection of the reaction products and of the residual reactants (118b). In a filter-press configuration, these two zones are respectively overlaid to the first calibrated holes to reach the active area of the reaction cells (101). |
