dc.description.abstract | The development of low-temperature solid oxide fuel cells (LT-SOFCs) as a mobile power source is attracting attention; however, limited understanding of rapid LT-SOFC operation constrains their use. Here, we present a high-performance LT-SOFC system capable of rapid thermal cycling and cold start-up, akin to ready-to-use. To achieve a ready-to-use LT-SOFC system, we modified a compact compressive sealing architecture implemented with a stacked disc spring, and a rapid thermal cycling with cold start-up was realized using a lamp heater. This LT-SOFC system reached target temperatures within 5 min of start-up and immediately exhibited an open-circuit potential of 1.124 V and a maximum power density of 1.123 W cm(-2) at 600 degrees C. We evaluated this system with harsh thermal cycling (25-500 or 600 degrees C) for 3000 min and confirmed its degradation behavior in perovskite phase separation and interfacial delamination. Our results provide another breakthrough in LT-SOFC development for mobile applications. | - |
