固体氧化物燃料电池（SOFC）是一种高效的固定式发电系统。固体氧化物燃料电池堆的高温余热可以回收用于热电联产。由于香港缺乏对固体氧化物燃料电池系统的相关分析，本研究旨在调查固体氧化物燃料电池-吸收式冷却热电联产/三联供系统在香港建筑应用的经济性。采用ICON酒店的能耗概况进行案例研究。选择现有的SOFC服务器和吸收式制冷机产品进行系统配置。结果表明，当政府补贴为系统总成本的50%时，三联产系统的投资回收期小于6年。敏感度分析显示，电价及政府补贴水平的增加会增加香港固体氧化物燃料电池系统的回收期。在香港推行建议中的热电联产╱三联产系统，除了技术上的困难外，还有法律的、社会的限制和空间的限制。本研究重点探讨固体氧化物燃料电池多联产在香港建筑应用的适用性及对环境的影响。
Solid oxide fuel cell (SOFC) is promising for efficient stationary power generation. The high temperature waste heat from SOFC stack can be recovered for cogeneration/trigeneration. Due to the lack of relevant analysis on SOFC system in Hong Kong, this research is purposely designed to investigate the economics of a SOFC-absorption cooling cogeneration/trigeneration system for building application in Hong Kong. Energy consumption profile of Hotel ICON is adopted for a case study. Existing products of SOFC server and absorption chiller are chosen to configure the system. It is found that the payback period is less than 6 years with the Government subsidy at 50% of the overall system cost for a trigeneration system. Sensitivity analyses show that increases in the rate of electricity and the level of government subsidy increase the payback period of SOFC systems in Hong Kong. Besides certain technological difficulties, obstacles on the way to realize the proposed cogeneration/trigeneration system in Hong Kong are legal and social constraints and space limitation as well. This study highlights the suitability and the environmental impact of the SOFC-based multi-generation for building application in Hong Kong.
