Patent ID: 7833680

Claim:
A method of making a fuel cell bipolar plate assembly, comprising: providing an anode plate; providing a cathode plate, said anode plate having a surface facing said cathode plate and a surface facing away from said cathode plate, and wherein said cathode plate has a surface facing said anode plate and a surface facing away from said anode plate; and securing a sheet of reinforcement material between said anode plate surface facing said cathode plate and said cathode plate surface facing said anode plate; defining at least one of said anode plate and said cathode plate with an active area having a plurality of grooves and an inactive area surrounding said grooves; covering only said inactive area with said sheet of reinforcing material and adhering it directly to both plates by an adhesive, said reinforcement plate having a manifold area defined by a plurality of openings in said inactive area in fluid communication with a plurality of aligned openings in said anode plate and cathode plate, said adhesive being located about said openings in said reinforcement plate; forming cooling channels by mating said plurality of grooves, in at least one of said anode or cathode plates, with one of said surfaces on either said anode or said cathode plates.
