基于林木热解产物的燃料电池制备与性能研究
Preparation and performance study of fuel cells based on wood biomass pyrolysis products
摘要
Abstract
Biomass pyrolysis can produce pyrolysis carbon and pyrolysis oil,of which the pyrolysis carbon is rich in surface functional groups and pore structures,while the pyrolysis oil contains a variety of components that can undergo redox reactions,which can be used for the preparation of fuel cell electrode materials and fuels,respectively.In this article,the working conditions of using wood pyrolysis oil as alkaline fuel cell fuel were optimized,and wood activated carbon(AC)and three types of wood pyrolysis carbon composite electrodes(AC/Fe,AC/Mn and AC/Fe/Mn)were prepared from wood pyrolysis carbon with K2CO3 activation and metal loading,furthermore the electrodes were analyzed using Fourier transform infrared spectroscopy,scanning electron microscopy,and electrochemical workstation.The microstructure,surface properties and electrochemical activity of the materials were analyzed by Fourier transform infrared spectroscopy and an electrochemical workstation.The results indicated that the optimal wood pyrolysis oil mass fraction and environmental temperature were 30% and 60℃,respectively,when AC was used as the cathode electrode,at this point the current reached 3.10 mA;under the optimized conditions,the currents for AC/Fe,AC/Mn and AC/Fe/Mn were 8.02,12.57,15.25 mA,which were 159%,305% and 392% higher than that of AC,respectively;under the optimized conditions,when AC/Fe/Mn was used as the cathode electrode and 12 mL of wood pyrolysis oil was added as the fuel,the fuel cell constructed from wood pyrolysis products could work continuously for 408.6 min with a total discharge capacity of 40.61 mAh.关键词
