The authors have developed a carbon dioxide reduction-water electrolysis tandem reactor as a new concept of ECLSS technology. Previously, the prototyped full-scale model achieved a hydrogen generation of ca. 3.6 L/min and the corresponding Sabatier reaction. This report presents the modification of both the Sabatier reaction part and the water electrolysis part in the full-scale reactor to improve the reactor's pressure conditions and the durability of the oxygen generation part.
