%X The work focuses on the research of porous storage material of a novel high-temperature rechargeable oxide battery (ROB). The ROB consist of regenerative solid oxide cell (SOC) and hydrogen/water vapor storage redox unit with embedded Fe/FeO porous redox material which has to meet the requirements, such as good kinetic properties, high oxygen storage capacity and high lifetime.
%X Because of long-term redox reactions at 800 °C the structure of the storage material can degrade, and thus makes the storage material incapable to store enough oxygen for continuous redox reactions. Due to that the Fe/FeO porous storage material has to be supported by e.g. inert and reactive oxides. To some extent the inert and stable mixed oxides show some resistance against structural degradation however, they could not completely provide a significant long-term oxygen storage capacity. In contrast to the stable oxides, reactive mixed oxides seem to be promising candidates which are capable to suppress a structural degradation after several redox cycles and improve the kinetic activity of Fe/MeO based storage material.
