| Outline of Final Research Achievements |
Surface of nano carbon materials such as carbon nanotubes (CNTs) and carbon nano horns (CNHs) were modified by ozone treatment using dielectric barrier discharge. The modified MWCNTs were used as electrodes material of polymer electrolyte fuel cell (PEFC) and the output characteristics of PEFC were investigated. XPS measurements revealed that functional groups containing oxyge were introduced on the surface of nano carbon materials by the ozone treatment.
The ozone-treated materials were used for the anode and/or cathode of PEFC. It was found that the output characteristic was extremely depended on the combination of electrodes material with and without ozone-treatment. Most highest output performance was obtained when the surface modified and the untreated carbon nano materials were used as the anode and chathode material, respectively. This result suggested that the use of ozone-treated nano carbon materials was effective for the improvement of output characteristic of PEFC.
