Problem

An experimental fuel cell has been designed that uses carbon monoxide as fuel. The overall reaction is

2CO (g) + O2 (g) → 2CO2 (g)

The two half-cell reactions are

CO + O2- → CO2 + 2e-
O2 + 4e- → 2O2-

The two half-reactions are carried out in separate compartments connected with a solid mixture of CeO2 and Gd2O3. Oxide ions can move through this solid at high temperatures (about 800°C). ΔG for the overall reaction at 800°C under certain concentration conditions is -380 kJ. Calculate the cell potential for this fuel cell at the same temperature and concentration conditions.
