摘　　要：选择Ce(SO4)2·4H2O与H2NCSNH为引发体系,控制反应温度为40℃,反应时间为6h等工艺条件,成功合成了一种新的质子交换膜燃料电池电极添加剂—阳离子聚电解质P(AM DMDAAC),其分子量在0.8×104～1.3×104范围内。通过测试阳离子聚电解质的电导率和研究循环伏安、热失重实验;结果发现,阳离子聚电解质P(AM DMDAAC)有良好的电化学性能和热稳定性。The cationic polyelectrolyte (P(AM-DMDAAC)) in a range of molecule weight from 0.8×10~4 to 1.3×10~4 was synthesized at 40 ℃ for 6 h. In this process, Ce(SO_4)_2·4H_2O and H_2NCSNH were used as the initiators. P(AM-DMDAAC) is a kind of new electrode additive for proton exchange membrane fuel cell. The electrochemical properties were studied on the basis of conductivity and cyclic voltammogram curves. In addition, the thermal stability of P(AM-DMDAAC) was investigated by analysis of TG curve. It is found that the electrochemical performance and thermal stability of P(AM-DMDAAC) is fine.
