Research status and advances of mobile solid oxide fuel cell system integration technology
Solid oxide fuel cells(SOFCs)are energy conversion devices that can convert the chemical energy in fuels into electricity through electrochemical reactions.At present,SOFC is mostly regarded as a stationary power generation technology.However,due to its fuel flexibility,high efficiency,and high energy density,it also has broad application prospects in the field of mobile power generation,such as auxiliary power,drone power,remote power supply,etc.Compared to the stationary applications of SOFCs,the progress toward the mobile applications of SOFCs starts relatively late and the technology is relatively incomplete.Mobile SOFC systems typically consist of SOFC stacks,fuel supply systems,oxygen supply systems,thermal management systems,and power management systems.When devel-oping SOFC mobile systems,system robustness,ease of use,and power generation capacity should be considered.However,the compo-nents of mobile SOFC systems are relatively complex,and the coupling and matching characteristics of these components will significantly affect the system compactness,startup characteristics,and volume/mass power density of the system.This paper provided a review of the domestic and international research progress on the integration technologies of mobile SOFC systems,covering aspects such as ther-mal characteristics,startup strategies,and the integration of high-power density hybrid systems.Finally,based on a summary of existing research findings,the challenges in the future integration of mobile SOFC systems were identified,along with such directions for development as improvements in materials and processes,the exploration of novel startup strategies,and the design and optimization of hybrid systems.
