Transient discharge simulation of a diffusion-limited

Hallo,

I am the beginner of COMSOL software.
Recently, I have a problem on doing transient discharge simulation of a diffusion-limited solid state cell.

I used Electrostatics and Transport of Diluted Species in my system. I want to simulate charged-anode part first, so I used cA as my variable. But I don't know it is correct or not.
After the simulation, the figure doesn't start from x=0 and it decreases repadily to zero, instead of diffusion a distance than decreases to zero.

I think the problem maybe on the boundary conditions but I don't understand how to work it. Does anyone has the experience on it?

Thank you very much
Liang
