제목 Electrochemical internal reforming of Carbon dioxide by Methane in SOFC System
초록 The CO2 catalytic reforming by CH4 is an attractive conversion technology because of the possibility of enhancing natural gas utilization with the sequestration of CO2. However this reaction has two serious problems such as the high energy consuming process and catalyst deactivation. To improve these problems, the electrocatalytic reforming of CO2 with CH4 was carried out in the SOFC system using electrochemical cells. Ni-YSZ-ceria based anode materials were prepared by precipitation method or physical mixing, and the electrochemical cells were manufactured by a tape casting method. The catalysts before and after the reaction were characterized by XRD, N2 Physisorption, SEM and TPD. It was found that Ni0.6YSZ0.4CeO2 |YSZ |(LaSr)MnO3 cell showed higher conversion than the other electrocatalytic cells under tested conditions.
