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。

预处理方法(建议)

杜邦公司提示:N117膜使用前可进行预处理,具体方法为:


- 首先将 Nafion117 膜在 80 °C 下、用5 wt.%的 H2O2 水溶液中处理 1h,以去除膜内的有机杂质。

- 其次用去离子水反复冲洗膜,将其浸泡在 80 °C 的去离子水中煮 1h,以完全除去残留的 H2O2。


(以下根据需求选择)

-再次将膜浸泡于 80 °C 、1.0 M 的H2SO4 溶液中煮 1h,通过离子交换将膜转为 H+型。

-最后用去离子水反复冲洗膜,将其浸泡在 80 °C 的去离子水中热处理 1h,以完全除去膜内残留的 H2SO4。此过程重复2-3次。


或者根据用户的既定习惯,只进行电解质溶液浸泡后使用,亦可。


保存

不用的时候,放到塑料袋里密封保存,避免受潮。

1. Strain Relaxation in Metal Alloy Catalysts Steers the Product Selectivity of Electrocatalytic CO2 Reduction

The bipolar membrane (Fumasep FBM) in this paper was purchased from SCI Materials Hub, which was used in rechargeable Zn-CO2 battery tests. The authors reported a strain relaxation strategy to determine lattice strains in bimetal MNi alloys (M = Pd, Ag, and Au) and realized an outstanding CO2-to-CO Faradaic efficiency of 96.6% with outstanding activity and durability toward a Zn-CO2 battery.
