    Electrochemical Cell Potentials.

    If you are setting up two of the same half cells (for example, Zn^2+(aq) / Zn(s)), how would you determine the cell potential of this? I know that Ecell = Ecathode - Eanode, but if the cell is the composed of the exact same half cells, does that make the cell potential 0? Thanks for any input.
