  Air-breathing proton exchange membrane fuel cells(AB-PEMFCs)have some advantages,such as small volume,high power densities,high energy conversion efficiency,clean and pollution free,making them ideal power sources for portable electronics or electric vehicles.To make the AB-PEMFCs technology commercial available,exploring and developing high performance cathode/air electrode has been the urgent issue.

A number of mechanisms that contribute to the cathode catalyst degradation have been proposed,including Pt particle sintering,Pt dissolution/re-deposition,and carbon support corrosion [1-3].However,it

目前,直接甲酸燃料电池(DFAFCs)的阳极催化剂中,性能好且稳定的还数Pt基催化剂[1-5].虽然就活性而言,尤其是在反应的初期,Pd基催化剂要高些,但其在酸性电解液中易溶解,并且随着时间的推移很容易失活等问题亟待解决.本工作通过在油胺和十八烯存在下,直接还原H2PtCl6·6H2O制备得到油胺功能化的具有特殊形貌---毛毛虫状的Pt纳米催化剂(Pt-OAm),电化学研究表明该催化剂对甲酸具有良

直接甲醇燃料电池(DAFCs)凭借其诸如低操作温度、易于运输、储存、高的能量密度和低污染排放等优良性能而广受人们关注[1-2].然而,现实中依然有一些难题阻碍DAFCs大范围商业化,尤其是阴极Pt催化剂在ORR中表现出一些潜在的问题,包括延缓的ORR动力学、由于醇类混合电位效应而导致的性能降低、差的稳定性等缺点,这已成为提高DAFCs性能的主要瓶颈[1-2].目前,在电催化剂设计中金属表面的非金属
