Preparation and Performance of Ni-CU/SDC Anodes

A series of Ni-Cu oxide solid solutions and Ce0.8Sm0.2O1.9 (SDC) electrolyte were synthesized by nitrate-citric acid method. Then Ni-Cu/SDC composite anode materials were prepared. Meanwhile, their microstructure and performance were also tested. The results showed that the single solid oxides fuel cell(SOFC) employing Cu0.4Ni0.6O as the anode, and using hydrogen as fuel had the best electrochemical performance. The maximal power density could reach 126mW.cm-2 at 700°C.
