摘要：

为提高固体燃料电池(solid oxide fuel cell, SOFC)的能源综合利用效率,提出一种基于SOFC循环、燃气轮机和吸收式制冷机的功冷联供系统。建立联供系统的热力学模型,给出设计工况下的热力学参数,对联供系统进行模拟分析。结果表明,在设计工况下,燃料电池发电效率、联供系统总发电效率和功冷联供效率分别为46.81%、54.53%和72.24%。燃料电池进口温度为620 ℃时,联供系统取得最大总发电效率和功冷联供效率,分别为54.66%和72.42%;在燃料电池进口温度为600 ℃时,联供系统输出制冷量最多。

Abstract:

In order to improve the energy utilization efficiency of a solid oxide fuel cell, a combined power and cooling system which integrated a solid oxide fuel cell, a gas turbine and an absorption chiller was proposed. A mathematical model was developed, and the thermodynamic parameters of the system were given to study the system performance under steady-state conditions. Results showed that, under the given conditions, the SOFC electrical efficiency, the total electrical efficiency of combined system and the power-cooling efficiency were 46.81%, 54.53% and 72.24%, respectively. When the SOFC inlet temperature was 620 ℃, the maximum total electrical efficiency of combined system and the maximum power-cooling efficiency were obtained 54.66% and 72.42%, respectively. When the inlet temperature of fuel cell was 600 ℃, the cooling capacity of the combined supply system was the largest.

Key words: SOFC, absorption refrigeration, thermal performance, combined power and cooling
