英文摘要	tin oxide nanocluster (sno2) with parallel nanorods was synthesized via a hard template method and explored as the anode catalyst support for proton exchange membrane fuel cells (pemfcs). single cell test demonstrated that sno2 supported pt catalyst (pt/sno2) exhibited comparable anode performance with conventional pt/c. electrochemical measurements showed that pt/sno2 exhibited significantly enhanced electrochemical stability than pt/c under high potential electro-oxidation and potential cycling. the pt/sno2 catalyst reserved most of its electrochemically active surface area (eca) under 10 h potential hold at 1.6 v while its eca degradation rate was one order of magnitude lower than pt/c under potential cycling between 0.6 and 1.2 v. therefore, sno2 nanocluster can be considered as a promising alternative anode catalyst support for pemfcs.
