reactions, concentration and fluxes

Hi friends,

I have a problem with flux boundary condition. I am using the electrolyte-electrode boundary interface as the boundary condition. The flux of ions is proportional to the current passes at electrodes.

What is surprising is that when the concentration of leaving ion reaches zero, comsol just continiues the flux condition without stopping that. so we have negative concentrations. Does it mean we cannot model diffusion-controlled kinetics with COMSOL?

Does anyone know a way to avoid this problem or to limit the current at certain conditions?

King regards,
