Electrode catalysts behavior during direct ethanol fuel cell life-time test
In the present paper, a 60 h life-time test of a direct ethanol fuel cell (DEFC) at a current density of 20 mA cm À2 (the beginning 38 h) and 40 mA cm À2 (the last 22 h) was carried out. After the life-time test, the MEA could not achieve the former performance. X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive X-ray analysis (EDX) were employed to characterize the anode and cathode catalyst before and after the life-time test. The XRD and TEM results showeddoi:10.1016/j.elecom.2005.04.021 fatcat:2fjjxzwftrdghobxkypcroeaia
