The present invention relates to SiC nanostructures, including SiC nanopowder, SiC nanowires, and composites of SiC nanopowder and nanowires, which can be used as catalyst supports in membrane electrode assemblies and in fuel cells. The present invention also relates to composite catalyst supports comprising nanopowder and one or more inorganic nanowires for a membrane electrode assembly.

Nanostructured catalyst supports

The present invention relates to nanostructured materials (including nanowires) for use in batteries. Exemplary materials include carbon-comprising, Si-based nanostructures, nanostructured materials disposed on carbon-based substrates, and nanostructures comprising nanoscale scaffolds. The present invention also provides methods of preparing battery electrodes, and batteries, using the nanostructured materials.

Nanostructured materials for battery applications

A catalyst layer for a fuel cell membrane electrode assembly includes a plurality of agglomerates, adjacent ones of the plurality of agglomerates contacting with each other with pores provided between said adjacent ones of the plurality of agglomerates, each of the plurality of agglomerates being formed by packing a plurality of catalysts each consisting of noble metal fine particles supported on a fiber-like support material, adjacent ones of the plurality of catalysts contacting with each other with pores provided between said adjacent ones of the plurality of catalysts, and each of the plurality of catalysts contacting with a plurality of catalysts other than said each catalyst at a plurality of contact points. This allows providing a catalyst layer, a fuel cell membrane electrode assembly, and a fuel cell, each of which has compact size and excellent power generation performance, and a method for producing the same.

Catalyst layer for fuel cell membrane electrode assembly, fuel cell membrane electrode assembly using the catalyst layer, fuel cell, and method for producing the catalyst layer

The present invention relates to electrochemical catalyst particles, including nanoparticles, which can be used membrane electrode assemblies and in fuel cells. In exemplary embodiments, the present invention provides electrochemical catalysts supported by various materials. Suitably the catalysts have an atomic ratio of oxygen to a metal in the nanoparticle of about 3 to about 6.

Electrochemical catalysts for fuel cells

The present invention is directed to nanowire structures and interconnected nanowire networks comprising such structures, as well as methods for their production. The nanowire structures comprise a nanowire core, a carbon-based layer, and in additional embodiments, carbon-based structures such as nanographitic plates consisting of graphenes formed on the nanowire cores, interconnecting the nanowire structures in the networks. The networks are porous structures that can be formed into membranes or particles. The nanowire structures and the networks formed using them are useful in catalyst and electrode applications, including fuel cells, as well as field emission devices, support substrates and chromatographic applications.
