摘要: A membrane-electrode assembly for use in thermoelectrochemical systems. The electrode assembly includes a radiation grafted cation exchange membrane which is plasma etched to provide an etched anode surface and etched cathode surface. A catalytic cathode layer is thermally bonded to the etched cathode surface and a catalytic anode layer is thermally bonded to the etched anode membrane surface. The resulting membrane-electrode assembly is resistant to delamination and provides electrochemical performance which is equal to or better than that obtained with more expensive conventional electrodialysis membranes.

摘要: A fuel cell system running on direct neat methanol. Back diffusion of water from the cathode to the anode is sufficiently high so that water is not accumulated at the cathode, thereby leading to fuel cell systems without the need for a pump system to remove circulate water from the cathode to the anode. Other embodiments are described and claimed.

摘要: An electrolyte membrane for use in a fuel cell can contain sulfonated polyphenylether sulfones. The membrane can contain a first sulfonated polyphenylether sulfone and a second sulfonated polyphenylether sulfone, wherein the first sulfonated polyphenylether and the second sulfonated polyphenylether sulfone have equivalent weights greater than about 560, and the first sulfonated polyphenylether and the second sulfonated polyphenylether sulfone also have different equivalent weights. Also, a membrane for use in a fuel cell can contain a sulfonated polyphenylether sulfone and an unsulfonated polyphenylether sulfone. Methods for manufacturing a membrane electrode assemblies for use in fuel cells can include roughening a membrane surface. Electrodes and methods for fabricating such electrodes for use in a chemical fuel cell can include sintering an electrode. Such membranes and electrodes can be assembled into chemical fuel cells.

摘要: A electrochemical immunosensor system is provided which uses electrical signals to measure binding events. The system includes an immunosensor having a sensing electrode in contact with a fluid containing an analyte concentration. A quantity of antibodies or other binding agent is adsorbed on or otherwise affixed to the electrode surface such that a portion of the antibodies of the binding agent binds a portion of the analyte to form complexes on the electrode surface. Signal generating means develop an electrical signal at the sensing electrode such that a response current is produced through the sensing electrode. The response current has measurable signal characteristics which are dependent upon the number of complexes formed, and therefore the analyte concentration within the fluid.
