    Noncovalent Functionalization of Single Walled Carbon Nanotubes Using Alternate Layer- By-Layer Polyelectrolyte Adsorption for Nanocomposite Fuel Cell Electrodes

    Electrodes which are resistant to chemical poisoning by CO, S, and other fuel impurities are needed to replace Pt in proton exchange membrane (PEM) fuel cells. We have designed composite electrodes comprised o...
