摘　　要：本文通过外电场来强化物质传输和提升热再生电池性能,研究了不同电场方向和强度对电池性能及效率的影响。结果表明,施加负电场(由阴极指向阳极的电场)强化了阴极反应物和阳极产物的传输,电池性能提升了20.8%。提升电场强度后发现电池的最大功率、产电电量及能量密度和热效率不断下降,这主要是由于进一步增加电场强度对阴极反应物和阳极产物的传输强化提升有限,但对阴离子跨膜传输的抑制作用增强,导致电池欧姆内阻增大。In this paper,the external electric field was used to enhance the material transport and improve the performance of thermal regenerative battery.The effects of different electric field directions and intensities on the performance and efficiency of the battery were studied.The results show that the application of a negative electric field(the electric field from the cathode to the anode)enhances the transmission of cathode reactants and anode products,and the battery performance is improved by 20.8%.After increasing the electric field intensity,it was found that the maximum power,electricity production,energy density and thermal efficiency of the battery continued to decrease,mainly because further increasing the electric field intensity limited the enhancement of the transmission of cathode reactants and anode products,but increased the inhibition of anion transmembrane transmission,resulting in increased ohmic resistance of the battery.
