Membrane electrochemical generator

The present invention relates to a membrane electrochemical generator () characterised by improved electrical insulation and reduced volume. The membrane electrochemical generator () is fed with gaseous reactants and comprises a multiplicity of reaction cells () assembled in a filter-press configuration. Each of said reaction cells () is delimited by a pair of bipolar sheets (), formed by a metallic central body () integrated in a frame () made of polymeric material. The polymeric material may be of the thermoplastic or thermosetting type and the frame () is laid on the metallic central body () by moulding.

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 ().

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 ().
