不同EW值的sPTFS/PTFE复合膜性能研究
, PP. 27-34
Keywords: 聚α,β,β_三氟苯乙烯,复合膜,EW值,质子交换膜燃料电池,电池性能
Abstract:
将两种不同EW值的聚α,β,β＿三氟苯乙烯(sPTFS)树脂浸入到多孔聚四氟乙烯(PTFE)膜的孔中,制成sPTFS/PTFE复合膜用于质子交换膜燃料电池(PEMFC).并对该复合膜的吸水率,电导率,机械强度及其装配的电池性能进行了测试.与其它均质膜相比,复合膜明显降低了吸水率,同时也降低了电导率,增加了机械强度.在电池温度为80℃,H2/O2压力为0.2/0.2MPa条件下,两种复合膜装配电池的性能优于Nofion115膜.低EW值的复合膜电池性能优于高EW值的电池性能,但电池稳定性相对较差.
