英文摘要	Conference Name:8th Symposium on Proton Exchange Membrane Fuel Cells. Conference Address: Honolulu, HI. Time:OCT, 2008.; The cobalt-polypyrrole (Co-PPy) composites adsorbed on the multiwall-carbon nanotubes (MWCNTs) were prepared by three methods. The structural, chemical and electrochemical properties of Co-PPy-MWCNTs samples were characterized by using XRD, SEM/EDX, element analysis, TG, FTIR, XPS, and cyclic voltammetry (CV). The results revealed that the Co-PPy was deposited on the MWCNTs surface and the ratios of Co/N for the three samples prepared differently varied. The conductivities and electrochemical catalytic activities of Co-PPy-MWCNTs samples were also affected by the different interactions between Co and PPy presented when using three preparation methods.
