摘要：

A series of La0.75Sr0.25Cr0.9M0.1O3 (M = Mn, Fe, Co, Ni) perovskite compounds was synthesized by a modified citrate sol-gel route and employed as anode electrodes on YSZ electrolyte supported SOFC cells. Materials and anode electrodes were characterized for their chemical composition, crystal structure and film morphology. The electrochemical performance of the prepared anodes was evaluated in button cells under SOFC operation with CO/CO2 mixtures in the temperature range of 900-1000 A degrees C. It was shown that the performance of the perovskite materials in terms of maximum power density follows the sequence Fe > Ni > Co > Mn, based on the substitution cation into the B-site. No carbon deposition was observed under the operating conditions examined, even for prolonged (120 h) exposure to the reaction mixture.
