    摘要： Novel proton exchange membrane fuel cells and direct methanol fuel cells with nanostructured components are configured with higher precious metal utilization rate at the electrodes, higher power density, and lower cost. To form a catalyst, platinum or platinum-ruthenium nanoparticles are deposited onto carbon-based materials, for example, single-walled, dual-walled, multi-walled and cup-stacked carbon nanotubes. The deposition process includes an ethylene glycol reduction method. Aligned arrays of these carbon nanomaterials are prepared by filtering the nanomaterials with ethanol. A membrane electrode assembly is formed by sandwiching the catalyst between a proton exchange membrane and a diffusion layer that form a first electrode. The second electrode may be formed using a conventional catalyst. The several layers of the MEA are hot pressed to form an integrated unit. Proton exchange membrane fuel cells and direct methanol fuel cells are developed by stacking the membrane electrode assemblies in a conventional manner.

    摘要： A hydrophilic coating can be optionally corrosion resistant and/or microbial resistant for a substrate such as a heat exchanger. The coating is provided by a zeolite layer that can be formed from a synthesis solution comprising a structure directing agent, a base, a silicon source, an aluminum source, and a solvent. In one preferred embodiment, the synthesis solution comprises tetrapropylammonium hydroxide, sodium hydroxide, aluminum oxide, tetraethylorthosilicate, and water. The layer is characterized by a zeolite MFI structure and by a composition having the formula of Mn/m[AlnSi(96−n)O192], or [AlnSi(96−n)O192]·4[(CH3CH2CH2)4N—OH] wherein M is a metal ion of valence m+ (e.g., Na+) and 27>n>=0. After formation of the coating, the organic structure directing agent can be left intact inside the zeolite coating to make the coating corrosion resistant. Alternatively, and after removal of the organic structure directing agent, a biocidal metal ion can be incorporated into the coating by an ion exchange process to render the coating microbial resistant. A hydrophilic coating that is also corrosion resistant and microbial resistant can be made by a zeolite coating with two sub-layers—the bottom sub-layer being corrosion resistant and the top sub-layer being microbial resistant.
