As part of the carried out work, a large-scale degradation model of solid oxide electrochemical cells operating in the reversible solid oxide cell mode (SOFC/SOE, i.e. rSOC - reversible solid oxide cell) was proposed. The tool takes into account: structural parameters of the cell at the micro scale, configuration and geometry at the meso scale, and cell performance and their operational characteristics at the macro scale. The degradation model was validated using experimental data and measurements carried out at the micro- and macro-scale. The use of a numerical tool made it possible to isolate and study degradation processes, taking into account the mode of conducting changes between the operation of the cell as the SOE and SOFC, and vice versa, the operating time in each mode and the temperature of the process. The proposed approach, based on a multi-scale simulation model, is used to optimize systems and microgrids in which rSOC cells, working with renewable energy sources, are operated in the mode of dynamic load change.

The research was conducted in cooperation with the Huazhong University of Science [&] Technology (Wuhan, China) and the Shenzhen Huazhong University of Science and Technology Research Institute (Shenzhen, China), as part of several projects. Issues regarding the boundary conditions of the electrolyser operation and degradation mechanisms by delamination of the air electrode are the subjects of research under the NEXTH2 project: Development of an innovative solid oxide electrolyser (SOE) produced by low-cost manufacturing techniques as a key element of modern energy storage systems based on the power-to-gas concept, financed under the LIDER XII program of the National Center for Research and Development (0003/L-12/2020).
