Recently, the CO2 reforming by CH4 to produce synthesis gas is becoming an attractive and challenge subject for the reduction and sequestration of CO2. However this reaction is a highly energy consuming process and coke forming process. To solve these problems, electrocatalytic internal reforming of CO2 by methane over the electrochemical cell (Ni-CeO2∥YSZ∥(La, Sr) MnO3) in SOFC system was investigated to coproduce a syngas and an electricity. The electrochemical cell was prepared by a tape casting method. The micro structure properties of the catalyst electrode before and after the electrocatalytic reforming were characterized by SEM. It was found that the reaction rates of CH4 and CO2, and the current density under the closed-circuit condition were stable after undergoing the electrocatalytic reaction for 3 h, whereas those of CH4 and CO2 under the open circuit slowly decreased. |
