001030408 520__ $$aThe adoption of fuel cell and hydrogen technologies will play a crucial role in facilitating the shift towards decarbonization and meeting the EU's goal of achieving zero net greenhouse gas emissions by 2050. In the coming years, particular emphasis will be placed on expanding the deployment of suitable hydrogen electrolyzers, such as solid oxide electrolysis cells (SOECs), which currently have a moderate technology readiness level (TRL 5-7). To support market entry and promote resource recovery, early-stage development and implementation of recycling strategies are imperative. Efforts are underway to address the reuse and recovery of components from high-temperature electrolyzers, focusing on the reprocessing of ceramic components from End-of-Life solid oxide cells (SOCs). Establishing closed-loop recycling processes is highly desirable, with a focus on scalability. In line with this objective, a recovery route has been devised for the well-established fuel electrode-supported cell design. The primary goal is to reprocess more than 80% of the cell material into new substrate, directly applicable in the SOC device. Therefore, a prerequisite step involves the separation of the oxygen electrode and any potential contact layer, which can be achieved through mechanical and/or hydrometallurgical approaches. Subsequently, the sintered bodies undergo reprocessing into ceramic powder, substrate slurry, and ultimately the pre-sintered substrate. Components of the separated oxygen electrode are recovered as precursors, suitable for SOC applications (e.g., manufacturing oxygen electrodes or contact layers) or alternative uses.In addition to presenting the properties of the recycled substrate, full cells were manufactured based on substrates containing 0%, 25%, and 50% recyclate by weight. Electrochemical tests were conducted to determine whether these substrates meet the functional requirements, including gas distribution, electrical conductivity, and mechanical stability.
