Fig. 3.

(A) Potential and power density curves as functions of the current density under 3% H2O/H2 (fuel electrode) and dry air (oxygen electrode) in FC mode. (B) Temporal evolution of the voltage at a constant current density of 0.3 A cm2 and 700°C in FC mode. (C) Potential curves as functions of the current density under 50% H2O/H2 (fuel electrode) and dry air (oxygen electrode) in EC mode. (D) Temporal evolution of the voltage at a constant current density of −1.1 A cm2 in EC mode, followed by continuous cyclic operation between FC (1.1 A cm2) and EC (−1.1 A cm2) modes at 700°C.
