Described herein are gas diffusion anodes, electrolytic systems comprising such anodes, as well as methods of using such systems. A gas diffusion anode comprises a current collector, an anode porous base, an anode catalyst layer, and an anode-liquid interfacing layer.

Resumen de: CN121507021A

本申请提供一种阴离子交换膜的制备方法及电化学装置。阴离子交换膜的制备方法包括：将阴离子交换树脂、增塑剂和溶剂混合，得到共混浆料；对共混浆料进行流延成型处理，得到共混膜；使用离子交换液对共混膜进行离子交换处理，得到阴离子交换膜。通过引入增塑剂，增塑剂与阴离子交换树脂在溶剂中共混形成共混浆料，在这个过程中，增塑剂会插入阴离子交换树脂的聚合物分子链之间，削弱聚合物分子链间的应力，增加分子链的移动性和柔软性，如此在共混浆料通过流延成型处理成为共混膜时，降低阴离子交换树脂的结晶度，并最终使得得到的阴离子交换膜不容易翘边。
