A reversible hydrogen/oxygen fuel cell operates at a constant temperature of 500

A reversible hydrogen/oxygen fuel cell operates at a constant temperature of 500 K. Stoichiometric amount of pure hydrogen and pure oxygen enters to the cell at 500 K and 80 bar, and the liquid water leaves the cell at the same temperature and pressure. Calculate the voltage of the cell (E value) and the cell efficiency. Assume hydrogen and oxygen are ideal gases. (Cp/R = A+BT)
