FUEL 253 |
| One of the most significant issues in the development of highly efficient fuel cells involves the design and synthesis of electrode materials and structure which serve to improve the electrocatalytic activity and decrease the amount of noble metal catalyst required. Various electrocatalyst nanoparticles, oxides, and supporting materials were synthesized by chemical methods and vacuum technique and their properties were characterized. Then novel nanocomposite electrode structures were designed and fabricated consisting of electrocatalyst, oxide, and supporting materials. The relationship between the electrode structure and electrocatalytic activity was studied. Membrane-electrode assemblies (MEAs) were fabricated using these nanocomposite electrodes and fuel cell performance was compared. Further technical issues on electrode structure in MEA will be presented. |
