Solid oxide fuel cells (SOFCs) have received considerable attention mainly for the high conversion efficiency and the capability of being powered by methane or biogas. Among the different routes for methane-syngas conversion, the dry reforming of methane (DRM) shows the combined advantages of syngas production and CO2 utilization. Besides it is extremely endothermic and it requires temperatures as high as those of operating SOFCs. Thus, SOFCs can operate in indirect internal reforming mode: simultaneously performing DRM reaction in their anode sides and, partly, compensating the energy necessary for the reforming with the heat released during the electro-oxidation. Nickel supported on samarium doped ceria (SDC) is a highly performing anodic material showing a remarkable electro-catalytic activity due to the presence of oxygen vacancies that promote the CH4 and CO2 activation for carbon suppression

Abstract
Solid oxide fuel cells (SOFCs) have received considerable attention mainly for the high conversion efficiency and the capability of being powered by methane or biogas. Among the different routes for methane-syngas conversion, the dry reforming of methane (DRM) shows the combined advantages of syngas production and CO2 utilization. Besides it is extremely endothermic and it requires temperatures as high as those of operating SOFCs. Thus, SOFCs can operate in indirect internal reforming mode: simultaneously performing DRM reaction in their anode sides and, partly, compensating the energy necessary for the reforming with the heat released during the electro-oxidation. Nickel supported on samarium doped ceria (SDC) is a highly performing anodic material showing a remarkable electro-catalytic activity due to the presence of oxygen vacancies that promote the CH4 and CO2 activation for carbon suppressionI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
