  2. Research Areas: Nanoparticles for Fuel Cells • Nanoparticle catalysts for PEMFCs • Nano-size precious and non-precious electrocatalysts with new compositions and novel nanostructures. • Facile techniques for Membrane Electrode Assemblies (MEAs) in PEMFCs and Scale-up in industry • One-step deposition method for integrated Gas Diffusion Electrodes (GDEs) by simple wet chemical methods.

  3. Research Areas: Nanoparticles for Fuel Cells Inorganic material study Preparation processes, characterization techniques, and the potential applications, etc. Nanoparticle aggregation analysis Molecular attraction between nanoparticles, protein and viruses.

  4. Polymer Electrolyte Membrane (PEM) Fuel Cell • Research background PEMFC House (With BAXI) PEMFC Car: (Micro:Cab) A clean power generator High cost; poor durability Electro-catalyst layer: Simple procedure and novel nanostructures PEMFC

  5. A facile procedure for catalyst layer • The normal method: three steps • A facile procedure for integrated Gas Diffusion Electrode (GDE) with Pt nanowires as catalysts on Gas Diffusion Layer (GDL) (J Power Sources195 (2010) 289) • One-step deposition method • Room temperature • Not using other catalysts or templates

  6. Pt nanowires grown on GDL • Images GDL before catalyst deposition As-prepared GDE Pt nanowires

  7. Electrochemical impedance spectra • Performance Commercial ETEK GDE 120E-W (BASF) As-prepared GDE with Pt nanowires

  8. Comparison of the power density • Performance
