SYMMETRICAL FLOW FIELD PLATES

摘要

The present invention relates to the design of flow field plates suited for use in electrochemical cells. According to aspects of some embodiments of the invention a true single plate bipolar flow field plate is provided. Moreover, according to other aspects of some embodiments of the invention active surfaces corresponding to an anode and a cathode, respectively, are substantially identical to one another, whereas in other embodiments the respective active surfaces are identical to one another after a transformation such as a reflection or 180 degree rotation.
