Abstract:
1. A fuel cell module comprising: an anode flow board comprising at least one anode board, an adhesive layer, and a flow board that provides flow path for fuel and reaction products, wherein said anode board comprises an anode supporting substrate having a printed circuitry formed thereon by printed circuit board processes and at least one anode charge collector fixed on said anode supporting substrate and said anode charge collector is electrically connected to said printed circuitry, wherein said adhesive layer bonds the anode board and the flow board; a cathode board comprising a substrate, at least one cathode charge collector and a plurality of through holes on said cathode charge collector, wherein said cathode charge collector is formed on two opposite sides of said substrate; a membrane electrode assembly (MEA) comprising at least one proton exchange membrane; an intermediate adhesive layer having a corresponding opening for accommodating said MEA; and a leak-proof adhesive layer mounted between said anode flow board and said MEA for preventing direct contact between the intermediate adhesive layer and said proton exchange membrane, wherein adhesion ability of said leak-proof adhesive layer to said proton exchange membrane is better than that of said intermediate adhesive layer to said proton exchange membrane; wherein said intermediate adhesive layer, said MEA, and said leak-proof adhesive layer are laminated together between said anode flow board and said cathode board, and wherein said MEA has two opposite sides that are in contact with said anode flow board and said cathode charge collector, respectively.
