Abstract

Experimental results on the development of two original approaches to obtaining new nanocomposite proton exchange membranes for low-temperature fuel cells are generalized. The first approach consists in in situ modification of the transport channels of commercial proton exchange membranes of the Nafion brand with interpenetrating polymer networks of the introduced polyelectrolyte based on cross-linked polystyrene sulfonate. The second approach is to create a proton exchange nanoscale phase based on polystyrene sulfonate in commercial hydrophobic polymer films. Polystyrene sulfonate is formed during thermal polymerization of styrene sorbed in the films without using ionizing radiation, followed by sulfonation. The influence of the conditions for obtaining membranes on the composition, morphology, transport properties, and results of testing the membranes in low-temperature fuel cells is considered.

制备燃料电池纳米复合质子交换膜的新方法

摘要

总结了开发两种新颖方法获得低温燃料电池用新型纳米复合质子交换膜的实验结果。第一种方法在于利用引入的基于交联聚苯乙烯磺酸盐的聚电解质的互穿聚合物网络，原位修饰Nafion品牌的商业质子交换膜的传输通道。第二种方法是在商业疏水性聚合物薄膜中创建基于聚苯乙烯磺酸盐的质子交换纳米级相。在不使用电离辐射的情况下，在膜中吸附的苯乙烯热聚合过程中形成聚苯乙烯磺酸盐，然后进行磺化。制膜条件对组成，形态，传输性能的影响，
