液中プラズマ法を用いたCNT表面へのPt触媒の形成とその燃料電池への応用

抄録

The in-liquid plasma was formed in the CNT dispersion by applying pulse high voltage between the platinum electrodes. The generated plasma spattered the surface of platinum electrodes and dispersed platinum particles in the CNT dispersion. The platinum with the weight of 21 mg was spattered by the applying pulse high voltage for 20 minutes. The spattered platinum particle was supported on the CNT surface. The platinum particles on the CNT were applied to the catalyst of the polymer electrolyte fuel cell. The open voltage of 0.91V and the maximum power of 1.47mW/cm² were observed for the fuel cell.
