Abstract
Pt/C catalysts supported on activated carbon, nano carbon, and multi walled carbon nanotubes were prepared by a one-step chemical reduction method. The factor of carbon carriers on the catalyst performance were studied in order to obtain the better cathode catalyst for direct ethanol fuel cells, and the nano carbon is the optimal support. Then, using nano carbon as the carrier, Pt-Fe and Pt-Co alloy catalysts with core-shell structure were prepared by the same method. The transition metals Fe, Co effects on the oxygen reduction performance and stability of the catalyst were investigated and compared with that of Pt/nano carbon catalysts. Finally, nano carbon supported Pt-Fe alloy catalysts shows the best performance which is better than commercial Pt/C catalysts. The process optimization of electrode preparation and single-cell assembly improved the cell performance, meanwhile increasing the experimental success probability.
