Abstract: Taking the third-generation fuel cell-solid oxide fuel cell(SOFC) as the research object, this paper made research on the
third-generation SOFC system based on new SOFC technology developed by German Siemens by choosing the design method that
combined internal and external fuel reforming, and made in-depth analysis and further optimization of the system when the design
working condition is 5 kW electrical efficiency by using system input exergy efficiency, energy utilization rate, fuel utilization rate,
and fuel cell inlet and outlet temperature as evaluation indicators. Compared with the original 5 kW working condition, the net
efficiency of the system has increased by 26%, the exergy efficiency has increased by 23%, the output power has increased by 2.5 kW,
and the overall energy utilization rate has increased by about 25%.
