摘要

Nafion聚合物膜是质子交换膜燃料电池(PEMFC)最常用的电解质材料，需要充分的水合作用才能达到高质子导电性。液态水的太赫兹(THz)辐射的衰减相对较高，因此可以观察到Nafion膜中水积聚的对比。本文研究了在Nafion聚合物膜中使用太赫兹相机进行液态水成像和定量的紧凑太赫兹系统的可行性。

Investigating liquid water distribution in Nafion polymer electrolyte membrane with terahertz imaging

Nafion polymeric membranes are the most common electrolyte material for proton exchange membrane fuel cells (PEMFC), requiring adequate hydration in order to reach high proton conductivity. The relatively high attenuation of terahertz (THz) radiation of liquid water enables a contrast to be observed for inspecting water build-up in Nafion membranes. This paper investigates the feasibility of a compact THz system using a THz camera for liquid water imaging and quantification in a Nafion polymeric membrane.
