Abstract
A bipolar or unipolar separator plate for an electrochemical fuel cell is formed of an insulating slab of plastic material such as a polymer matrix having a plurality of electrically conductive elements embedded therein for conducting electricity from an adjacent electrode of the cell to an electrical conductor on the opposite side of the slab for deriving electricity from the cell. The conducting elements are preferably formed of aligned carbon fiber composite cylinders and the insulating slab is formed of a plastic such as epoxy, polyamide, polystyrene, polyphenylene oxide or polyphenylene sulfide molded around the conductive elements.
