The article Control-oriented dynamic process optimization of solid oxide electrolysis cell system with the gas characteristic regarding oxygen electrode delamination, was published in the highly rated journal Applied Energy (IF 11,446), presenting the results of work carried out to reduce delamination of the air electrode during operation in unsteady states.
The article Control-oriented dynamic process optimization of solid oxide electrolysis cell system with the gas characteristic regarding oxygen electrode delamination, was published in the highly rated journal Applied Energy (IF 11,446), presenting the results of work carried out to reduce delamination of the air electrode during operation in unsteady states.
As part of the work, a 2D model of a solid oxide electrolyser (SOE) was built, which was used for variant analysis. In the course of the analysis, the composition and volumetric flow of inlet gases to the electrolyser as well as the operating temperature and pressure were changed. Temperature gradients and partial pressure of oxygen in the interface between the electrolyte and the air electrode, which is mainly responsible for delamination of the cell, were analyzed. The results of the work allowed to define strategies for controlling the operation of electrolysers under dynamic load change conditions in order to minimize the conditions leading to their degradation. The co-author of the publication is prof. Jakub Kupecki, DSc, PhD.
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. The issues of the boundary conditions of the electrolyser operation and the mechanisms of degradation by delamination of the air electrode are the subject of research as part of the project NEXTH2: Development of an innovative solid oxide electrolyser (SOE) produced with low-cost manufacturing techniques as a key element of modern energy storage systems based on the power-to-gas concept, financed under the programme LIDER XII National Center for Research and Development (0003/L-12/2020).
