From the background written above, we are focusing adapting full-scale CO2reforming (dry reforming) to SOFC systems to expand the capability of SOFCs. To reveal the feasibility of the dry reforming SOFC system, we have previously investigated the performance and durability of catalysts (reformer) and a cell stack in simulated dry reforming by comparing with that of steam reforming.
In this study, we investigated the performance of SOFC hotbox adapting dry reforming. The thermally self-supported state was successfully demonstrated in dry reforming operation. Additionally, this study discusses the heat balances of a hotbox under dry and steam reforming conditions. From the obtained results, we will introduce the problem and capability of the dry reforming SOFC system and discuss its feasibility.
