Expediting electrochemical reactions that involve gaseous components is crucial for the development of diverse energy and environmental applications (batteries, electrochemical conversion, fuel cells, and gas sensors). Unfortunately, the intrinsically closed structure of conventional electrochemical cell systems, in which a liquid (or solid) electrolyte exists between the electrodes, does not allow the facile and direct diffusion of gaseous reactants or products to/from the electrode surface. Our design, an electrochemical cell system with an open-structured form factor, involves an “aeroelectrolyte” that floats in the air and directly approaches the electrode surfaces. The electrochemical system contains a nonwoven nanofiber salt bridge to ensure continuous and stable electrochemical reactions in the aeroelectrolyte-based cells. We confirmed the feasibility of our design in a modified Daniell cell by varying the factors that affect the aeroelectrolyte and electrode components. Our open-structure electrochemical system with the aeroelectrolyte enables the realization of ideal three-phase boundaries for atmospheric electrochemical reactions.

用于大气开放式电化学电池的空气电解质
加速涉及气体成分的电化学反应对于多种能源和环境应用（电池、电化学转换、燃料电池和气体传感器）的发展至关重要。不幸的是，传统电化学电池系统的固有封闭结构（其中电极之间存在液体（或固体）电解质）不允许气态反应物或产物轻松且直接地扩散至电极表面或从电极表面扩散。我们的设计是一种具有开放结构外形的电化学电池系统，涉及漂浮在空气中并直接接近电极表面的“空气电解质”。该电化学系统包含非织造纳米纤维盐桥，以确保基于空气电解质的电池中连续稳定的电化学反应。我们通过改变影响空气电解质和电极组件的因素，证实了我们在改进的丹尼尔电池中设计的可行性。我们的开放式结构电化学系统与空气电解质能够实现大气电化学反应的理想三相边界。
