SOFC Durability against Standby and Shutdown Cycling
Journal of the Electrochemical Society
To simulate realistic operating conditions in SOFC systems, we investigate the influence of thermal cycling on the performance of electrolyte-supported planar SOFCs. Thermal cycling is often associated with interruption of fuel supply, with three main modes; hot standby, cold standby, and shutdown. Cell performance degradation is most significant during shutdown cycles. Nickel oxidation and agglomeration are more pronounced when SOFCs are subjected to lower temperatures for longer periods ofdoi:10.1149/2.0421409jes fatcat:w5xge7ybjvdhhlpeyvoc3vr5ym
