Abstract
A preparation method of a direct ethanol fuel cell includes synthesizing electrolytes, preparing a cathode and an anode, and clamping the electrolytes between the cathode and the anode to get direct ethanol fuel cell. The electrolytes are synthesized by polymerizing sodium acrylate with an initiator to get a hydrogel, and the hydrogel is soaked in a harsh alkaline solution. The cathode is synthesized by coating N,S codoped carbon catalyst onto a current collector, where the N,S codoped carbon catalyst is synthesized by mixing and preheating silica powder, sucrose and trithiocyanuric acid to get a mixed powder, and mixing and heating the mixed powder with poly tetra fluoroethylene so as to get the N,S codoped carbon catalyst. The anode is synthesized by coating Pt-Ru/C catalyst onto a current collector.
