Nanostructured materials, for fuel cell

Nanostructured Li and Ni containing nickel-metal hydride batteries are widely used in cell phones, video camcorders, quartz watches, and pacemakers to name a few uses. Electrically conducting nanostructured mesoporous materials are envisaged as new materials for fuel cell applications, batteries, and ultracapacitors.

In summary, the controlled synthesis of CNTs, CNFs, and NWs is critical in order for them to be used in practical applications. In particular, the nanostructures grown on carbon paper are ideal materials for fuel cell electrodes. In the next sections, we will focus on how to use them in fuel cells.

Fig. 1.1 A novel vision of refueling/retail station for fuel cell-powered vehicles based on the concept of the off-board recharging of spent hydride fuel and the mechanochemical synthesis of nanostructured hydrogen storage materials in ball-mill plants. Such is not the currently accepted vision of hydrogen economy but one which may turn out to be viable alternative to onboard...

The last three chapters are dedicated to improving the durability of the catalyst/ electrode. Chapter 22 reports the development and evaluation of bimetallic Pt-Ru (Ir) oxygen evolution catalysts on 3M s nanostructured thin film (NSTF). This type of catalyst may significantly reduce carbon corrosion and Pt dissolution during transient conditions of fuel cells. Chapter 23 discusses the unique properties of carbide-modified carbon as the support for fuel cell catalysts. The final chapter gives a comprehensive review of novel materials other than carbon black as catalyst support. The interactions between the supports and catalysts are intensively discussed in the last two chapters. 

Nanostructured TiOj has also been utilized as PEMFC catalyst supports with dimensions well below 100 nm. Like other TiOj structures, these materials also inherit high stability, high surface areas, and moderate electrical conductivity. Titanium oxide nanotubes are of particular interest for fuel cell catalyst supports due to their abihties to form porous networks, disperse catalytic metals upon the surface...
