The application discloses a SOFC integrated power generation system containing a diesel pretreatment unit, and belongs to the technical field of solidoxidefuel cells. The SOFC integrated power generation system at least comprises a diesel pretreatment unit, a SOFC power generation unit and an intelligent controlsystem. The pretreatment unit converts diesel into high-purity hydrogen-rich gas through desulfurization, denitrification and autothermal reforming processes. The SOFC power generation unit adopts a metal support type stack and realizes efficient power generation in combination with heat management. The intelligent controlsystem can realize real-time monitoring and dynamic adjustment to ensure stable operation of the system. The power generation efficiency of the SOFC integrated power generation system can reach 55% to 58%, the fuel utilization rate reaches more than 90%, and the emission is low. The SOFC integrated power generation system is suitable for distributed power generation, mobile power sources, emergency power sources and automobile fuel cells and the like application scenarios, and has the characteristics of high efficiency, environmental protection and stability.
