文摘

Novel SSOFCs with redox-reversible cermet electrodes are proposed. Ni0.7Co0.3O-Ce0.8Sm0.2O1.9 (NC-SDC) is used as new SSOFC electrode materials. NC-SDC cermet electrode is confirmed to be completely redox-reversible. SDC buffer layer dramatically enhances the electrochemical performance. Redox-reversible cermet electrodes open doors for SSOFC development.
