How to find the voltage without current density

Please login with a confirmed email address before reporting spam

Hello everyone, I am working on diffuse double layer with charge system. I use 1D model to simulate the electrode/electrolyte interface which similar to the COMSOL example. I input electrode voltage on anode is V and on cathode is 0[V]. From the example, they use integral of current density to find the variable voltage, V. In my case, I don't have the information about current density, is it possible to find V in other way, instead of integral of current density? It will be nice to receive any comment and suggestion.

Thank you

Liang
