Keeping the advantages of symmetrical solid oxide fuel cells (SSOFCs) with redox-stable electrodes, novel SSOFCs with redox-reversible cermet electrodes are proposed to solve the major problems of low electronic conductivity (<10−1) under anode atmosphere and poor electrochemical activity for fuel oxidation. The conventional Ni0.7Co0.3O-Ce0.8Sm0.2O1.9 (NC-SDC) cermet anode is applied simultaneously as a potential redox-reversible cathode for SSOFCs with practical yttria-stabilized zirconia (YSZ) electrolytes. The electrochemical performance of SSOFCs with NC-SDC cermet electrode can be improved via SDC buffer layers and the corresponding maximum power density increases from 140.1 mW cm 2 to 200.2 mW cm−2 at 800 °C. The new redox-reversible cermet electrodes of SSOFCs open doors for development of next-generation SSOFC electrode materials.
