A fuel cell module includes an anode flow board, a cathode board, an intermediate adhesive layer, a membrane electrode assembly (MEA) including a membrane edge, and a leak-proof adhesive layer mounted on the membrane edge, thereby preventing contact between the intermediate adhesive layer and the membrane edge. The adhesive ability of the leak-proof adhesive layer to the membrane edge is higher than that of the intermediate adhesive layer to the membrane edge. Therefore, the methanol leakage from the membrane can be avoided.

Fuel cell module

A wave-shaped flow board suitable for a fuel cell includes an injection-molded body substrate, a reaction zone recessed into a surface of the body substrate, and a wave-shaped current collector, which defines a plurality of independent fuel channels. The wave-shaped current collector is integrally mounted in the reaction zone and comprises a bendable conductive lug portion for providing an electrical connection between the wave-shaped current collector and a circuit on the surface of the wave-shaped flow board.

Wave-shaped flow board of fuel cells

A flow board suited for fuel cell applications. The flow board includes a body substrate formed by injection molding methods, which is resistive to methanol or chemical corrosion and has superior mechanical properties. The flow board further includes a wave-shaped reaction zone having thereon a plurality of independent fuel channels. The body substrate and the wave-shaped reaction zone may be monolithic. Alternatively, a punched electrode plate affixed on the reaction zone may define the plurality of independent fuel channels.

Wave-shaped charge collection plate of fuel cells and method of making the same

A fuel cell module includes a cathode board, an integral flow board integrated with a plurality of wave-shaped anode plates and membrane electrode assembly (MEA) interposed between the cathode board and the integral flow board. The integral flow board has a body substrate that is formed of ejection moldable polymers by using ejection-molding techniques. The wave-shaped anode plate defines a plurality of independent flow channels and is fittingly affixed in corresponding reaction zone of the body substrate.
