Membrane electrochemical generator

摘要

The present invention relates to a membrane electrochemical generator ( 200 ) formed by a multiplicity of reaction cells ( 201 ) 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 ( 200 ) and the hydration of the membrane ( 204 ) 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 ( 230 ) obtained in conductive bipolar plates ( 203 ) delimiting the reaction files ( 201 ). The cooling fluid can be preheated by passing through a collector/distributor structure ( 206 ) located in an additional cell ( 202 ).
