Design and analysis of residential solid oxide fuel cell combined heat and power supply system

固体氧化物燃料电池(SOFC)发电技术是一种能够直接将燃料中的化学能转化电能的绿色高效的新能源技术。将SOFC作为分布式能源的发电装置运用在家用热电联供系统,具有综合效率高、无污染、无噪声等优点。文章搭建了天然气重整制氢-SOFC热电联供系统,完成了基于SOFC的家用热电联供系统的设计与分析。文章根据用户夏冬季热电消耗数据,提出了一种以用户电消耗为核心的家用热电联供系统的运行方案,同时给出了蓄电池容量和水箱容积的推荐参数。与传统火力发电系统相比,采用天然气的SOFC热电联供系统更加节能。

Solid oxide fuel cell （SOFC） power generation technology is a green,efficient and new energy technology which can directly convert the chemical energy of the fuel into electric energy. SOFC is a distributed generation of power generation devices used in domestic cogeneration system, with some advances such as high efficiency, pollution-free, no noise and so on. This paper sets up the natural gas reforming hydrogen-SOFC combined heat and power supply system to complete the design and analysis of the domestic combined heat and power supply system with SOFC. According to the data of spring and summer thermoelectric consumption, this paper presents a operation scheme of domestic combined heat and power supply system which focus on consumer electricity consumption, and gives the recommended parameters of battery capacity and tank volume. Compared with traditional thermal power generation, natural gas-based SOFC cogeneration system is more energy efficient.
