Abstract

As climate change intensifies, weather patterns across the globe become far less patterned and more unpredictable. Instances of extreme heat, excessive rain resulting in floods, and droughts that may cause or intensify wildfires have severely stressed centralized water treatment and distribution facilities and compromised access to fresh water for many. Given the vast reserve of saltwater, desalination technologies that can separate the dissolved salts from the fresh water have become essential. Traditional desalination methods use either membrane or thermal-based technologies to separate solutes from salt water and brackish water that have typical concentrations of 35,000 and 1,000 mg/L, respectively. However, they can be unnecessarily energy-intensive for lower salinity conditions. A potential next-generation approach is desalination fuel cells. Desalination fuel cells have the capability to simultaneously desalinate water and produce energy.
电化学在行动-海水淡化
随着气候变化的加剧,全球各地的天气模式变得越来越不规律,越来越不可预测。极端高温、过量降雨导致洪水,以及可能导致或加剧野火的干旱,都给集中式水处理和分配设施带来了严重压力,并影响了许多人获得淡水的机会。鉴于盐水储量巨大,能够将溶解的盐从淡水中分离出来的海水淡化技术变得至关重要。传统的脱盐方法使用膜或基于热的技术从盐水和微咸水中分离溶质,盐水和微盐水的典型浓度分别为35000和1000mg/L。然而,对于较低盐度的条件,它们可能是不必要的能量密集型。一种潜在的下一代方法是脱盐燃料电池。脱盐燃料电池具有同时脱盐和产生能量的能力。
