Electrochemical reactions such as water splitting, fuel cell, and ammonia synthesis have recently received intensive attention because of environmental friendliness. In such systems, the ion-exchange membrane (IEM) is one of the main components determining their efficiency. IEM is to allow permeation of desired ions but blocks unwanted species. Generally, the ion transport behavior of IEMs strongly depends on their microstructure such as the size of the ionic channel or the density of ionic domains. However, it is under veils for the detailed correlation between ion permeation characterization and physicochemical and morphological properties of commercial Nafion® membranes. This poster aims to characterize how membrane structural parameters influence ion permeation properties. To do so, we have used a customized diffusion cell, which can simultaneously measure anionic and cationic permeation properties. More details will be addressed in this poster. |
