The present invention relates to a membrane electrochemical generator () formed by a multiplicity of reaction cells () mutually connected in electrical series and assembled according to a bipolar configuration. In accordance with the present invention, the thermal management of the membrane electrochemical generator () and the hydration of the membrane () are ensured by the injection of a cooling fluid, preferably liquid water, in the gaseous reactant feed. Such an injection takes place through a multiplicity of calibrated fluid injection holes () obtained in conductive bipolar plates () delimiting the reaction files (). The cooling fluid can be preheated by passing through a collector/distributor structure () located in an additional cell ().

Membrane electrochemical generator

A membrane electrochemical generator comprises a multiplicity of reaction cells () 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 (), which comprises a multiplicity of first calibrated holes () for the passage of the gaseous reactants and a multiplicity of second calibrated holes () for the discharge of the reaction products and of the optional residual reactants. The cooling cells () comprises a rigid peripheral portion (), whereupon a gasket () is laid, defining and sealing on each face of such peripheral portion a zone of collection of the gaseous reactants () and a zone of collection of the reaction products and of the residual reactants (). 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 ().
