TECHNOLOGY FOCUS - POLYMERS - Preferred Component: Additional layers comprising sheets of polyimide material are also included. The porous membrane comprises a polyamide layer having an array of 104 channels/cm2. It comprises a plastic material having pores with diameter less than 1 mum and a thickness of 10-100 mum.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The flowing mechanism comprises a fuel inlet, a porous membrane, and a fuel outlet. The polyimide sheet is positioned between the porous membrane and the anode forms a seal between the porous membrane and anode. The removing mechanism comprises at least one of microchannel communicating with the cathode. An additional sheet of polyimide material forms a seal between the microchannel and cathode. The MEA comprises 3 Nafion layers containing anode and anode catalyst materials. The third Nafion layer contains a cathode and cathode catalyst material. Two polyimide layer having at least one microfluidic device are embedded between the two layers. The microfluidic connection device is capillary tubing. The polyimide layers comprise pump(s) embedded between the two layers and valve(s) embedded between the two layers. A fifth polyimide layer supports the anode manifold and contains a fifth layer fuel feedthrough communicating with a fourth layer fuel outlet. It forms a seal between the porous membrane and anode. The connecting mechanism comprises vias in each layer filled with a conductive material, preferably silver epoxy. Preferred Property: The membrane electrode assembly operates at less than 200degreesC. The width of the channel is less than 10 mum. The thickness of polyimide layer is 25-200 mum. The system has a power output of 0.1-20 Watts, preferably 100 mWatts to 20 Watts. Preferred Process: The bonding is accomplished by ramping the oven to 305degreesC over 150 minutes at approximately 2degreesC/min. The bonded polyimide fuel cell is cured by heating to 120degreesC.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The anode and cathode comprise carbon cloth. Preferred Composition: The catalyst material comprises platinum-ruthenium in a ratio of 50-100% platinum and 0-50% ruthenium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The fuel is a methanol-water mixture comprising hydrogen, carbon dioxide, and less than 1% carbon monoxide.
