Due to their high flexibility andefficiencies, especially using power-heat-coupling, Solid Oxide Cells(SOCs) are showing off to be a promising technology on an industrialscale.As every material-based technology SOCs face the increasinglyrelevant question of resource efficiency and critical raw material use.This results in the necessity of developing recovery strategies along thewhole life cycle – from the raw material procurement to the End-of-Life(EoL) or End-of-Use (EoU) state. Large potential lays also within therecycling of waste material during the cell manufacturing process.Recovery methods for all major types of SOCs are still not developedto scalable strategies however there already exist first concepts for theseveral types as shown in a recent overview publication by Sarner et al.[1].Using the example of the fuel-electrode supported SOC, first recyclingsteps with respect to the green support layer composed of Ni(O) andstabilized zirconia (YSZ), the sintered support layer with the adjacentfuel electrode (Ni(O) / YSZ fine grained) and finally as complete half-cell including the YSZ electrolyte have been characterized on the basisof a master thesis performed in 2022.While direct recycling of untreated substrate green tapes shows off tobe possible by re-suspending it with solvent, the recovery of sinteredmaterial – substrate and half-cells – comes along with a slight influenceon sintering behavior and microstructure, nevertheless seems to be afeasible way, especially using tailored recyclate fractions.[1] Sarner S., Schreiber A., Menzler N.H., Guillon O.
