Abstract:	The oxygen pumping characteristics of the solid electrolyte material (Bi0.75Er0.25)2O3with gold and platinum electrocodes have been studied by three-electrode I–V measurements. These experiments show only little influence of the electrode material used on the electrode behavior. Exchange current density values are high and are confirmed by 18O2 exchange data on the bare electrolyte. This leads to the conclusion that (Bi0.75Er0.25)2O3 has good properties for oxygen pumping applications and is an electrochemically active material in oxygen transfer processes.
