A method of making a bipolar plate includes molding a non-conductive
housing defining a plurality of receiving areas. A first plurality of
conductive charges are located into each of the plurality of receiving
areas. Compressive force is applied to each of the first plurality of
conductive charges thereby defining a first plurality of conductive
plates bonded on outer edges to the non-conductive housing. A second
plurality of conductive plates are located onto the first series of
conducive plates. The first and second plurality of conductive plates are
bonded together defining a coolant flow field therebetween.
