摘要： In an AMFC, in the formation of a CCM, the anode catalyst layer is selectively cross-linked while the cathode catalyst layer is not cross-linked. This has been found to provide structural stabilization of the CCM without loss of initial power value for a CCM without cross-linking.

摘要： A method for forming a carbon supported catalyst includes a step of providing a first carbon supported catalyst having a platinum-group metal supported on a first carbon support. Characteristically, the first carbon support has a first average micropore diameter and a first average carbon surface area. The first carbon supported catalyst is contacted with an oxygen-containing gas at a temperature less than about 450° C. for a predetermined period of time to form a second carbon supported catalyst, wherein the first carbon support or the second carbon supported catalyst is acid leached.

摘要： Cohesive carbon assemblies are prepared by obtaining a carbon starting material in the form of powder, particles, flakes, or loose agglomerates, dispersing the carbon in a selected organic solvent by mechanical mixing and/or sonication, and substantially removing the organic solvent, 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, or discs, having high carbon packing density and low electrical resistivity. The method is suitable for preparing adherent cohesive carbon assemblies on substrates comprising various materials. The assemblies have various potential applications, such as electrodes or current collectors in electrochemical capacitors, fuel cells, and batteries, or as electromagnetic interference shielding materials.

摘要： A method for manufacturing an alloy catalyst for a fuel cell is disclosed. The method for manufacturing an alloy catalyst for a fuel cell may include predetermined processes and reaction conditions, such that iridium is alloyed to platinum contained in a cathode carbon support catalyst. Accordingly, time for stabilizing charge on the carbon surface may be reduced and a metal particle size may be controlled, thereby manufacturing high quality products having uniform metal particle distribution and improved durability. In addition, corrosion of a cathode carbon support catalyst in a harsh condition such as vehicle driving may be prevented.

摘要： A solid oxide fuel cell has anode, cathode and electrolyte layers each formed essentially of a multi-oxide ceramic material and having a far-from-equilibrium, metastable structure selected from the group consisting of nanocrystalline, nanocomposite and amorphous. The electrolyte layer has a matrix of the ceramic material, and is impervious and serves as a fast oxygen ion conductor. The electrolyte layer has a matrix of the ceramic material and a dopant dispersed therein in an amount substantially greater than its equilibrium solubility in the ceramic matrix. The anode layer includes a continuous surface area metallic phase in which electron conduction is provided by the metallic phase and the multi-oxide ceramic matrix provides ionic conduction.
