He meant that the max potential occurs when there is little to no current because that is when the potential difference in the galvanic cell is at its maximum, since it decreases over time when the current flows through the cell. Maximum potential means the most energy available to do work, which can be represented by E not and calculated by the standard reduction potentials of the oxidation reduction half reactions.
Maximum work occurs right before current flows because immediately when current begins flowing, the electric potential begins to decrease until it reaches zero. So, when asked a question about maximum potential, it is right before the circuit is closed or right before any reaction begins.
Max potential occurs right before the cells are connected because the electric potential is the greatest (nothing is flowing between them.) As time goes on, the system heads towards equilibrium and the electric potential decreases.

Could you explain the relationship between maximum voltage and how there is the least amount of current flowing? What is the implication and meaning of little current flowing? Thank you!
