www.comsol.com/model/model-of-a-diffuse-double-layer-13525, which is based on the Paper web.mit.edu/bazant/www/papers/pdf/Bazant_2005_SIAM_J_Appl_Math_MTF2.pdf .
This might sound like an unusual question, but I'm regarding the dimensionless charge density -Why is the Charge density across the domain asymmetrically distributed? i.e, close to the Cathode, it reaches 0.6, while on the Anode, it reaches -1.8. I'm not really able to understand what is the physical reason behind this. Mathematically, I can see that the distribution of Anions is an exponential curve dependent on Potential, which is inherently asymmetric, but even then, shouldn't the distribution of Cations and the distribution of Anions be 'inverses' of each other? I have attached an image of the plot that I'm referring to.
