abstract = {Fuel Cells and Electrolyzers will play a significant role
in the futureenergy system and industry. 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.,
