Fuel cell bipolar plates with multiple active areas separated by non-conductive frame header

摘要

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.
