Patent ID: 7597984

Claim:
A method of making a bipolar plate comprising: molding a non-conductive housing defining a plurality of receiving areas: locating a first plurality of conductive charges into each of said plurality of receiving areas, said housing including an intake header and an exhaust header that connect a plurality of inlet and outlet apertures to the respective plurality of receiving areas; applying compressive force to each of said first plurality of conductive charges thereby defining a first plurality of conductive plates bonded on outer edges to said non-conductive housing, each late of said first plurality of conductive plates having a first reactant flow field that fluidly communicates with said intake and exhaust headers; locating a second plurality of conductive plates onto said first series of conductive plates, each plate of said second plurality of conductive plates having a second reactant flow field that fluidly communicates with said intake and exhaust headers; and bonding said first and second plurality of conductive plates together defining a coolant flow field therebetween.
