 Whether formula_19 is greater than formula_6 is dictated by whether (formula_13-formula_14 ) or formula_23 is greater than formula_24 .The internal oxygen partial pressure is minimized by increasing the electronic resistance at the anode interface and decreasing the ionic resistance at anode interface.Delamination of the anode from the electrolyte increases the resistance of the cell and necessitates higher operating voltages in order to maintain a stable current.
