Solid oxide fuel cells (SOFCs) and solid electrolyzer (SOECs) represent a promising clean energy solution. In the case of SOFCs, they offer efficiency minimal to zero CO2 emissions when used convert chemical into electricity. When SOFC systems are operated in regenerative mode for water electrolysis, SOFCs become (SOECs). The problem with these is supply availability raw materials SOEC components. This raises significant economic challenges has an impact on price scalability technologies. Recycling that make up can alleviate by reducing dependence overall costs. From this point view, work perspective analysis examines current research recycling materials, highlighting potential paths towards circular economy. existing literature different approaches key components SOECs important. Mechanical separation techniques isolate components, along strategies like leaching or hydrometallurgical material characterization, ensure quality recycled reuse new important as well. By evaluating various methods recovered study aims provide valuable insights advancing sustainable economically viable technologies within net-zero framework.

R&D in the area of high-temperature symmetrical electrochemical devices is needed to meet challenges hydrogen energy. In present study, effect Fe2O3 and CuO sintering aids on properties highly conductive solid electrolyte La0.8Sr0.2Ga0.8Mg0.2O3−δ La0.6Sr0.4FeO3−δ electrodes for oxide fuel cells was investigated. It shown that use leads an improvement grain boundary conductivity allows us reduce temperature obtain a dense with same level conductivity. first time nature affect electrode activity differently depending gas environment (air or hydrogen). On basis analysis impedance spectra by distribution relaxation times, assumptions were made about rate-determining steps oxidation oxygen reduction. can change temperature. found among studied electrodes, 3 wt.% sintered at 1050 °C optimal terms oxidizing reducing atmospheres.
