Abstract:
A fuel cell is provided, including an integrated cathode/anode flow board, a first anode current collector, a first cathode current collector, a first membrane electrode assembly, a second anode current collector, a second cathode current collector, and a second membrane electrode assembly. The integrated cathode/anode flow board includes first cathode channels for air to flow through, and a plurality of first anode channels for a fuel to flow through. The first cathode channels and the first anode channels are disposed on opposite sides of the integrated cathode/anode flow board. The first anode current collector contacts the first anode channels. The first membrane electrode assembly is sandwiched between the first anode current collector and the first cathode current collector. The second anode current collector contacts the first cathode channels. The second membrane electrode assembly is sandwiched between the second anode current collector and the second cathode current collector.
Abstract:
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.
Abstract:
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.
Abstract:
A fuel cell system includes a fuel cell stack consisting of a plurality of fuel cell units, a flow-distributing device, and a flow-confluence device; a fuel container; a housing encompassing and protecting the fuel cell stack and the fuel container; and a fan mounted on the housing for providing air to the cathodes of the fuel cell units. The fuel cell units have liquid inlet and liquid outlet, which are connected with the flow-distributing device and the flow-confluence device respectively.
Abstract:
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.
Abstract:
A prepreg for fuel cell obtained by soaking reinforcing glass fiber cloth in resin mixture and having the soaked cloth pre-dried to form incompletely cured prepreg which can be press-cured under temperature range of 60□˜200□ to provide good mechanical and electrical property and high bonding strength, and when applied to fuel cell for bonding together the parts and components of the fuel cell the prepreg can also provide the effect of preventing crossover of fuel of the fuel cell and helping to the normal operation of the fuel cell.
