Thermal management is an important technology for ensuring the normal operation of submarine data centers. Aimed at the special working environment of a submarine data center, the solid oxide fuel cell (SOFC) is used as its emergency power source, and an SOFC thermal management system model with seawater as the only coolant is improved. Then, the total heat dissipation model and dynamic thermal model of SOFC are established, the fuzzy control strategy used for SOFC is optimized by a genetic algorithm, and the implementation effects of non-dominated sorting genetic algorithm-II (NSGA-II) and other algorithms are compared based on MATLAB. Finally, the temperature distribution and average current density of the power stack under different voltages are analyzed in simulation experiments. Experimental results verify that the improved thermal management method can effectively improve the heat dissipation efficiency of the SOFC system in the submarine data center and ensure its safe operation, which is helpful for improving the operation stability of the submarine data center.
