Abstract
In order to reduce the low effective utilization of the combined thermal power supply system caused by the abnormal energy distribution, the design of the electric conversion and energy storage integration of SOFC combined power supply system based on feature fusion is proposed. The design of internal combustion engine, heat storage device and battery is carried out. Based on the system temperature, SOFC heat exchanger model is established. The energy state in the heat exchanger model is analyzed and judged by feature fusion. According to the results, the energy is converted, stored and released. The experimental results show that the energy utilization efficiency of the system can reach 81.57%, which is 36.9% higher than the source system, which has good application value.
