| Outline of Final Research Achievements |
A sputtering system specialized in thin film formation of catalysts alternative to Pt, such as ZrON and TaON, on fine particles of carbon was developed. ZrO2 and ZrON thin films were formed on fused quartz plates, and characterized by X-ray diffraction and photo-absorption spectroscopy. Oxygen reduction reaction starting potential was evaluated by cyclic voltammetry. Some films are found to have high catalytic ability close to an ideal value.
If the technique for thin film formation directly on fine particles of carbon heated above 1100K is established, these alternative catalysts can be supported on practical membrane electrode assemblies, which will contribute to full-fledged popularization of polymer electrolyte fuel cell in instead of Pt.
