| 英文摘要 | two pt/c catalysts with different particle sizes (pt/c: 2.5 run, pt/c-700ar: 5.1 nm) were investigated by applying a half-cell configuration - rotating disk electrode (rde) technique in h2so4, aqueous solutions in the absence of or in the presence of methanol with different concentrations. pt/c catalyst exhibited higher mass activity in h2so, aqueous solution without methanol and slightly lower mass activity in h2so4 plus 0.1 mol/l ch3oh in comparison with that of pt/c-700ar catalyst. on the contrary, single direct methanol fuel cell (dmfc) tests showed that pt/c exhibited higher oxygen, reduction reaction (orr) activity and better cell performance, mainly due to the different kinds of electrolyte properties. furthermore, it suggested that a better single dmfc performance could be obtained with a smaller particle size pt-based cathode catalyst. |
