摘要
为了降低由于甲醇渗透导致的电池性能损失,合成了具有阻醇作用的Pt纳米颗粒,并将其用于对Nafion膜的改性.实验结果表明:同原来的Nafion膜相比,Pt/Nafion改性膜具有更低的甲醇渗透率,在高温及高浓度甲醇的测试条件下,表现出更优异的电池性能.
Nafion has been modified by applying platinum nanoparticles as methanol barrier materials to decrease methanol permeation and improve the performance of fuel cells.The modified membrane shows improvement on reducing methanol loss and the DMFC performance of modified membrane is superior to that of bare Nafion under high temperature and high concentration of methanol.
