“…A Ni based catalyst is employed also in the fuel steam reformer. According to Dokmaingam et al [58] and Kim-Lohsoontorn et al [59], this is directly coupled to the SOFC stack, in an IIR-SOFC (Indirect Internal Reforming-SOFC) configuration. This geometry allows to obtain an efficient direct transfer of the heat dissipated by the exothermic electrochemical reactions occurring in the SOFC stack, to the endothermic methane steam reforming reaction taking place in the adjacent steam reformer.…”

We investigate failure incidents of a solid oxide fuel cell (SOFC) system during start-up from ambient conditions as well as during operation around the design point, using numerical simulation with a view to performance and thermo-mechanical stresses. During start-up, which comprises heating and load ramping phases, the system's trajectory moves through a relatively large temperature range. The simulated failure scenarios include reversible operational discontinuities in terms of input parameters and irreversible hardware failures. Furthermore, we also present results for a complete power cut. A multiphysics modeling approach is used to couple thermal, electrochemical, chemical, and thermo-mechanical phenomena by means of time-dependent partial differential, algebraic, and integral equations. Simulations revealed that the system can smooth out thermal discontinuities that are within a few minutes, that is, within the range of its thermal inertia. However, during the initial phase of the start-up procedure, thermo-mechanical stresses are relatively high due to larger differences between the sintering (manufacturing) and operation temperature, which makes the system more susceptible to failure. This work demonstrates that a multiphysics approach with control-and reliability-relevant aspects leads to a realistic problem formulation and analysis for practical applications.
