And Migration

Using electrochemical impedance spectroscopy (EIS), we observed the rate of water dissociation decrease in the presence of salt ions while also observing the diffusion and migration of these salt ions, showing a clear link between the peaks observed in EIS and ion crossover. In addition, we show how EIS can be used to in-situ monitor the stability and ageing of a BPM, revealing that degradation of the BPM is more prominent in extreme pH electrolyte pairs compared to non-extreme electrolyte pairs. The in-situ monitoring of the WDR and stability of a BPM are vital methods for adequate and consistent comparison of novel designs of BPM-based systems, where EIS allows for discriminating BPM characteristics from other components even during operation. <br>
