| Fuel cells and biofuel cells are currently attracting more and more interests from academies and industries. Catalyst and configuration design are key issues for high performance fuel cells. Meanwhile, recent advances in nanoscale science and technology enable us to manipulate the catalyst in nano level. It appears that nanoscale engineering of the biocatalysts is greatly promising for the development of high performance biofuel cells. Our preliminary experimental research in biofuel cells will be discussed in this presentation. Glucose oxidase electrodes were prepared via forming composites with carbon fibers, carbon nanotubes and nanoporous carbon materials. Significant enhancement on electrochemical flux and reaction kinetics was observed on the composite-modified glassy carbon electrode by cyclic voltammetry. When the resulting electrodes were applied in a model glucose/O2 biofuel cell as the anodes, a power density up to about 900 mW/cm2 was achieved. By using functional carbon nanofibers, higher performance is expected. |
