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).

摘要： A membrane fuel cell stack characterised by a stable operation under non-humidified air feed at the cathode inlet with a stoichiometric factor higher than 1 and near ambient pressure, even at high current density. This result is obtained by means of an air feed conditioning device comprising a fan or little compressor, a heat exchanger directed to cool the compressed air and an expander allowing to cool the air while recovering part of the energy consumed by the fan.

摘要： The membrane electrochemical generator (100) is fed with gaseous reactants and comprises a multiplicity of reaction cells (101) and a multiplicity of cooling cells (102) mutually connected in series and assembled according to a filter-press type configuration. Each reaction cell (101) is delimited by a pair of conductive bipolar plates (103) comprising 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), in their turn, comprise 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 (113a) and to the second calibrated holes (113b). During the operation of the electrochemical generator (100), the gaseous reactants flow to the zone of collection of the gaseous reactants (118a), passing therefrom through the multiplicity of upper calibrated holes (113a) to reach the active area of the reaction cells (101). The reaction products and the residual reactants produced in the reaction cell (101) pass in their turn through the multiplicity of lower calibrated holes (113b) to reach the zone of collection of the discharge products (118b) exiting the electrochemical generator (100) therefrom.
