PLAQUE D'EXTREMITE POUR PILE A COMBUSTIBLE, INTEGRANT DES ELEMENTS DE GESTION D'UN FLUIDE CALOPORTEUR.

摘要

An end plate has a structural block with an inner side supported on a stack of bipolar plates and ion exchange membranes and a complementary outer side (B11). The inner side has two orifices (P5w, P7w) connected to a coolant circuit located in the cell. The block has a chamber (P1w) forming coolant supplying manifold, delimited by walls of the block and extending between the orifices. A plate (E11w) is positioned and mounted inside the chamber, in a sealed manner on a wall of the chamber and has recirculation orifices to ensure the circulation of a coolant selectively towards the orifices.
