Solid oxide electrolyzer cells pose a promising technology for the production of hydrogen gained from renewables, such as wind and PV. Due to the fluctuating nature of these sources, the transient behavior of SOECs under various load cases plays a crucial role in terms of their long-time stability, degradation behavior, conversion efficiency and application. This study presents a dynamic, 2D-FEM model of a single tubular SOEC. The transient operational behavior of the cell under fast load variations and different flow configurations is assessed based on the conducted simulations.
•Development of a transient 2D model of a tubular SOEC.•Examination of the cell behavior for different load variation speeds.•The use of different load switching speeds is proven insufficient for advanced cell control.•Counter-current flow configurations lead to moderate temperature gradients inside tubular cells.
