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.

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.

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.
