Cation exchange membrane (CEM) (anion exchange membrane (AEM)) is located at lower (upper) side of the channel, and ratio of channel width to length is 1:5 in both experiment and simulation. In the experiment, local ion concentration was tracked with 10-\u00b5M Rhodamine 6G (R6G), and circular depletion boundary layers dbl are observed as a dark region caused by depletion of R6G (Figure 2(a)); in simulation, ion depletion is represented as a blue region (Figure 2(c)). Fluid flows were visualized by stacking time-lapse images of 10-\u00b5m polystyrene (PS) beads (Figure 2(b)).
