| 英文摘要 | cobalt based non-precious metal catalysis were synthesized using chelation of cobalt (ii) by imidazole followed by heat-treatment process and investigated as a promising alternative of platinum (pt)-based electrocatalysts in proton exchange membrane fuel cells (pemfcs) transmission electron microscopy (tem) x-ray diffraction (xrd) and x-ray photoelectron spectroscopy (xps) measurements were used to characterize the synthesized con(x)/c catalysts the activities of the catalysts towards oxygen reduction reaction (orr) were investigated by electrochemical measurements and single cell tests respectively optimization of the heat-treatment temperature was also explored the results indicate that the as-prepared catalyst presents a promising electrochemical activity for the orr with an approximate four-electron process the maximum power density obtained in a h(2)/o(2) pemfc is as high as 200 mwcm(-2) with con(x)/c loading of 20 mg cm(-2) (c) 2010 elsevier ltd all rights reserved |
