摘要： Methods and devices are provided for the continuous production of a network of nanotubes or other nanoscale fibers. The method includes making a suspension of nanoscale fibers dispersed in a liquid medium, optionally with surfactant and/or sonication, and filtering the suspension by moving a filter membrane through the suspension, such that the nanoscale fibers are deposited directly on the filter membrane as the fluid medium flows through the filter membrane, thereby forming a continuous membrane of the nanoscale fibers. The deposition of the nanoscale fibers can occur when and where the filter membrane moves into contact with a static, porous filter element or a dynamic, porous filter element. The filtering can be conducted within a magnetic field effective to align the nanoscale fibers, and/or with the aid of vacuum to pull water through the filter membrane, applied pressure to press water though the filter membrane, or a combination thereof.

摘要： A membrane electrode assembly (MEA) for a fuel cell comprising a catalyst layer and a method of making the same. The catalyst layer can include a plurality of catalyst nanoparticles, e.g., platinum, disposed on buckypaper. The method can include the steps of placing buckypaper in a vessel with a catalyst-precursor salt and a fluid. The temperature and pressure conditions within the vessel are modified so as to place the fluid in the supercritical state. The supercritical state of the supercritical fluid containing the precursor salt is maintained for period of time to impregnate the buckypaper with the catalyst-precursor salt. Catalyst nanoparticles are deposited on the buckypaper. The supercritical fluid and the precursor are removed to form a metal catalyst impregnated buckypaper.
