Role of silver current collector on the operational stability of selected cobalt-containing oxide electrodes for oxygen reduction reaction

► Current collecting ways affect the long-term stability of SSC and BSCF electrodes. ► Mesh-like current collector (CC-02) shows a stable current collecting performance. ► BSCF and SSC show stable electrode performance with CC-02 current collector. ► Phase transition does not affect activity of BSCF for oxygen reduction reaction.
