  Ethanol fuel cells and methanol fuel cells are a new type of electrochemical energy,which has the characteristics of high energy density and low environmental pollution,and has important research significance in the current environment where resources are scarce.The electroactivity of the catalyst directly affects the performance of the direct alcohol fuel cell(DAFC).Therefore,the improvement and research on the performance of the catalyst is currently the focus of international attention.In this paper,a soft template method was used to prepare carbon hollow sphere precursors by hydrothermal reaction.Nickel-cobalt-nitrogen doped carbon hollow spheres(NixCoy/N-CHS),a solid catalyst,was prepared by doping a certain proportion of nickel-cobalt-nitrogen into the precursor,taking anhydrous ethanol as the solvent and Nafion solution as the binder,dispersed into a catalyst coating and coated on the glassy carbon electrode,and then characterized by means such as SEM.At the same time,the electrocatalytic activity of catalyst on alcohol(methanol and ethanol)was analyzed by Cyclic Voltammetry(CV),Chronoamperometry(CA)and electrochemical impedance spectroscopy(EIS) methods.
