| contents | The intermittency of solar and wind power can be addressed by integrating them with Solid Oxide Cells (SOCs). This study delves into the transient characteristics of SOCs and their dependence on dynamic heat and mass transfer processes. Non-dimensional analysis was used to identify influential parameters, followed by a 3-D numerical simulation-based parametric analysis to examine the dynamic gaseous and thermal responses of SOCs with varying dimensions, material properties, and operating conditions. For the first time, we proposed characteristic times to describe the relationship between SOC transients and multiple parameters. These characteristic times represent the overall heat and mass transfer rats in SOCs. Their effectiveness was validated against literature and demonstrated potential in characterizing the transient characteristics of other electrochemical cells. Besides, two examples are provided to illustrate how the characteristic times facilitate SOC design and control at minimal computational cost. |
