1. 介绍
Nafion膜用于分隔质子交换膜燃料电池和水电解槽的阳极室和阴极室。这种特殊的阳离子交换膜Nafion N117的厚度使其适合直接甲醇燃料电池(DMFC)。Nafion 117的厚度为183微米。
Chemours(以前称为DuPont)Nafion 117膜是非增强膜,基于化学稳定的酸(H +)形式的全氟磺酸/ PTFE共聚物。化学稳定膜的物理性能保持不变,与非稳定聚合物相比,其释放的氟离子大大降低,这是化学耐久性得到改善的标志。Nafion PFSA膜广泛用于质子交换膜(PEM)燃料电池和水电解槽。该膜在各种电化学电池中充当隔膜和固体电解质的角色,这些电化学电池需要该膜选择性地将阳离子转运穿过整个细胞结。该聚合物具有耐化学性和耐用性。
