Special Issue Information
Dear Colleagues,
Based on the core component stack, SOFC (solid oxide fuel cell) power generation systems are equipped with BOP (balance of plant) subsystems, which have the characteristics of electrical–thermal strong coupling, large time delay in thermal characteristics, and difficult control. As medium–high-temperature, high-efficiency power systems, the most important thing for SOFC systems is to meet the load requirement while maintaining thermal safety, a long life, and high efficiency.
In order to commercialize solid oxide fuel cells so that they can operate with the aforementioned qualities, the operating as well as dynamic and static characteristics of the system need to be evaluated to obtain the optimal static operating point and dynamic and static switching trajectory. At the same time, it is necessary to identify possible faults in the system in time to prevent them from damaging the system’s performance. Finally, corresponding control strategies should be developed for the operating characteristics of the battery and possible faults to ensure efficient and stable operation of the system.
The electrical reactor response time is milliseconds, the gas delivery response time of the BOP subsystem is seconds, and the temperature response time is minutes, and there is a time lag in the gas delivery and thermal response, which can make it difficult to track the load of the SOFC system. Dynamic changes in operating conditions increase the technical difficulty of optimizing system efficiency, which may also lead to failures such as thermoelectric oscillations, fuel deficits, carbon deposits, and system temperature overruns. Thus, system performance degradation or failure leads to the invalidation of the original control algorithm, and the SOFC system goes out of control, which in turn hinders the long-life and high-efficiency operation of the system.
The current research on dynamic analysis and management of SOFC systems is deficient in the following aspects. One is that thermal characteristic constraint modeling and analysis are incomplete. The other is that there is no quantitative analysis and verification method to support the realization of system thermoelectric coordinated optimization control under system degradation.
The purpose of this Special Issue is to collect research papers and reviews on “Control, Diagnosis, and Evaluation of Solid Oxide Fuel Cells” in order to reflect the latest trends and challenges in this topic. The scope of this Special Issue includes the integration of real SOFC systems, the construction of SOFC thermoelectric coupling models, the study of algorithms for SOFC performance evaluation and fault diagnosis, and the design of controllers for SOFC health management.
