A multi-criteria assessment of a solid oxide fuel cell (SOFC)-based polygeneration is presented. Taking a residential area in Malaysia as the case study, the polygeneration is integrated with the photovoltaic thermal and thermoelectric generator as the most applicable heat recovery devices to be combined with a solid oxide fuel cell (SOFC). The proposed recovery system is compared with the basic heat recovery system, which only employs a heat exchanger and an absorption chiller. The simulation study is conducted for the systems investigating the improvement in terms of energy, economic and environmental criteria.

From the results, it reveals that the proposed heat recovery system achieves an efficiency of 11.38% higher and the grid consumption of 12.85% lower than the basic recovery system when the system was applied for grid-connected with electric vehicle supply attached. Moreover, the proposed system can reduce the carbon emission by 31.60% and 30.32% as compared to polygeneration with the basic heat recovery system and the separated system, respectively.

提出了基于固体氧化物燃料电池（SOFC）的多代发电的多标准评估。以马来西亚的一个居民区为例，多联产与光伏热电发电机集成在一起，成为最适用的热回收设备，与固体氧化物燃料电池（SOFC）结合使用。将拟议的回收系统与仅使用热交换器和吸收式冷却器的基本热量回收系统进行了比较。对研究能源，经济和环境标准方面的改进的系统进行了仿真研究。

从结果可以看出，当该热回收系统用于附有电动车电源的并网系统时，其效率比基本回收系统高11.38％，电网消耗低12.85％。此外，与采用基本热回收系统和分离式系统进行多联产发电相比，所提出的系统可分别减少31.60％和30.32％的碳排放量。
