This paper presents a comprehensive overview on the current status of solid oxide fuel cell (SOFC) energy systems technology with a deep insight into the techno-energy performance. In recent years, SOFCs have received growing attention in the scientific landscape of high efficiency energy technologies. They are fuel flexible, highly efficient, and environmentally sustainable.
Heat management and load tracking are two crucial tasks for solid oxide fuel cell (SOFC) systems development. In literature, plenty of temperature controllers and load tracking controllers have been successfully designed for SOFC systems. However, previous researches are limited to control design in the case of SOFC normal conditions. For a SOFC system, faults can occur

The size of the 8.4MW SOFC system is similar for the five carriers as expected. The dynamic performance of the LOHC system shows that the hydrogen flow rate can be effectively controlled by acting on the LOHC flow rate, reactor temperature, and pressure. However, LOHC systems are heavier (by a factor of 1.6 to 2.1) and larger (by 1.6 to 2.3
The two SOFC systems considered have a nominal power output of in the range of 10.7 kWe electric and 16.4 kW thermal at 40 C return flow water temperature. Both SOFC systems can be modulated down to 4.4 kWe electric and 2.7 kW thermal output.

This is one case where a materials development could be an enabling technology that might dramatically reduce the cost of the SOFC system and push the state-of-the-art one step closer to the SECA target. However, even in cathode and anode materials, some potential exists to increase SOFC performance and drive down costs.

Unlike the SR-SOFC system, the selection of different fuels as reforming feedstock in the DR-SOFC system results in significant differences in the actual output voltage of the SOFC, with the order of voltage magnitude being consistent with the order of H 2 concentration in the reformate.

Solid oxide fuel cells (SOFCs) can in theory utilize such fuels in a high efficient manner, which could reduce greenhouse gas emissions and energy demand. However, SOFC systems able to directly utilize diesel are rather complex to design and monitor, leading to several possible causes of system lifetime reduction.
