Outline of Final Research Achievements

Surface of nano materials such as multi-walled carbon nanotubes (MWCNTs) were modified by ozone treatment using dielectric barrier discharge in oxygen atmosphere. The modified MWCNTs were used as electrodes material of polymer electrolyte fuel cell (PEFC) and the output characteristics of PEFC were investigated.FTIR and XPS measurements revealed that functional groups of carboxylate ion were introduced on the MWCNTs surface by the ozone treatment. The ozone-treated MWCNTs were used for the anode and/or cathode of the PEFC. It was found that the output characteristic was extremely depended on the combination of electrodes material with and without ozone-treated MWCNTs. Most highest output performance was obtained when the surface modified and the untreated MWCNTs were used as the anode and chathode material, respectively. This result suggested that the use of ozone-treated MWCNTs was able to improve the output characteristic of the PEFC.
