摘要： Cohesive carbon assemblies are prepared by obtaining a functionalized carbon starting material in the form of powder, particles, flakes, loose agglomerates, aqueous wet cake, or aqueous slurry, dispersing the carbon in water by mechanical agitation and/or refluxing, and substantially removing the water, typically by evaporation, whereby the cohesive assembly of carbon is formed. The method is suitable for preparing free-standing, monolithic assemblies of carbon nanotubes in the form of films, wafers, discs, fiber, or wire, having high carbon packing density and low electrical resistivity. The method is also suitable for preparing substrates coated with an adherent cohesive carbon assembly. The assemblies have various potential applications, such as electrodes or current collectors in electrochemical capacitors, fuel cells, and batteries, or as transparent conductors, conductive inks, pastes, and coatings.

摘要： Disclosed are a process for separating an electrode for membrane-electrode assemblies of fuel cells from the decal transfer film and an apparatus for separating the electrode. In particular, during the electrode separating process, only an electrode is separated from the decal transfer film on which the electrode is coated, without any damage, by a freezing method for freezing the specimen on the deionized water surface, and thus, wasting the expensive MEA is prevented. Thus, mechanical properties of the pristine electrode can be rapidly quantified in advance, and therefore, long term durability evaluation period during developing MEA having excellent durability is substantially reduced.
