Thermodynamic performance study of the integrated MR-SOFC-CCHP system

The fossil energy crisis is a great test for human society and the prospect of methanol reforming hydrogen fuel cell technology is of great concern. Higher production cost is also an important factor in limiting the combined cycle power plant. The integrated system enables the overall energy utilization efficiency to improve. Methanol can be made from coal gasification and liquefaction and coal chemical industry has received the attention and support from the state and it is an extremely promising technology. Based on the large scale commercial process simulation software Aspen Plus, this paper constructs a distributed energy system based on solar methanol reforming SOFC which combines GT-ST power generation system with AHP-AR. The results show that the efficiency of SOFC, total electrical efficiency and total system thermal efficiency of the method are 35%, 66% and 90% respectively. In this paper, the performance analysis of SOFC integrated system is carried out which reveals the affinity of solar energy and chemical energy. The results show that the new system increases the power generation and reduces the coal consumption rate.
