Development of CO2 Conversion Technology for Internal Reforming of CO2 by CH4 in SOFC System |
| 초록 |
Nickel-based catalyst is used mainly as anode material for internal reforming in solid oxide fuel cell(SOFC). However, this catalytic reaction is a highly energy consuming and coke forming process. These problems can be overcome by the electrocatalytic reforming of CO2 with CH4 in a SOFC system, which generate high electrical power and synthesis gases. Under the open-circuit condition, the reaction rates of CH4 and CO2 drastically decreased. It was considered that the daactivation was caused by carbon deposition on catalyst electrode. On the other hand, the reaction rates of CH4 and CO2 were stable after undergoing the electrocatalytic reaction for 3 h under the closed-circuit. It was found that the conversions of CO2 and CH4 electrochemical cell (NiO-YSZ-CeO2｜YSZ｜(La,Sr) MnO3) are 30% and 35% respectively, and maximum power density is 50 mW/cm2 at 100 mA/cm2. |
