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 molding.

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 ().
