### cell potential

is there a maximum cell potential that can be reached?

Yes! The max potential of a cell is the maximum potential difference between two half reactions in a galvanic cell. I think you can calculate this by manipulating different equations.

### Re: cell potential

The maximum cell potential occurs at the instant when the anode and cathode are first connected and the flow of electrons begins. Beyond that point, the concentrations in the half-reactions change. The production of product decreases the cell potential per increasing Q in the Nernst equation: E= E^0 -RT/nF ln Q.

### Re: cell potential

Cell potential is greatest when the cell reaction first begins to occur. Following this, the concentrations change and the potential is no longer at its maximum value.
