To mitigate carbon emissions from grid electricity, utility-scale zinc-air fuel cells are deployed as a backup energy storage solution. Under standard operating conditions, each cell delivers a stable nominal potential of 1.65 V through the oxidation of zinc. If the air supply is maintained but the zinc anodes in the cells are completely consumed such that the system reaches thermodynamic equilibrium, what will be the terminal voltage across each cell?
1.65 V1.65\text{ V}1.65 V
0.83 V0.83\text{ V}0.83 V
0.00 V0.00\text{ V}0.00 V
−1.65 V-1.65\text{ V}−1.65 V
