【Abstract】 A novel sodium polysulfide/bromine regenerative fuel cell (PS Br RFC) with polyarylonitrile graphite felt electrodes was developed. The catholyte and anolyte while separated by a cation exchange membrane. When the RFC is discharging, the sulfide and lower polysulfide compounds are oxidized into corresponding higher polysulfide compounds in the anolyte while the bromine are reduced into bromide in the catholyte respectively. However, when the RFC is charging, the electrochemical reaction process is reversed. Effects of membrane, tem perature and concentration of electrolyte on the performance of RFC were investigated systematically. The results show that the polyarylonitrile graphite felt is a perfectly active material for both the half cell reactions. The power density output of 0.3 W/cm 2 (V=1.0 V) is obtained from this novel energy storage system. The study of cyclic performance show that the RFC maintains good performance during the whole charge/discharge cycles and its performance deterioration is low.更多还原
