Micro-scale distributed power generation system, which means a micro-cogeneration system in almost cases, has been paid a great attention from a standpoint of saving fossil fuels' consumption and preventing global warming. Especially, polymer electrolyte fuel cell (PEFC) is considered the most promising power generation system for small scale commercial use and residential use.In the PEFC cogeneration system, small amount of waste heat at low temperature from a cell stack is almost used to produce hot water. Therefore, in the study, the head investigator proposed a new heat utilization method of the waste heat for air conditioning. In the proposed home cogeneration system, absorption refrigerator has been introduced in order to produce chilled water. So, a new low concentration solution cycle was contrived and its COP was estimated, and the COP is used in the numerical simulation for developing both a high performance and compact absorber.Thermal performances of the proposed system have been analyzed by a computer simulation which was developed for the prediction both of power generation characteristics of PEFC and absorption refrigerator's behavior. Performances and efficiencies of the total system were predicted quantitatively and compared to that of actual proof test machines. Furthermore, on basis of the past experimental results, the performance prediction of the novel vertical plate type absorbers have been carried out in order to find new techniques that could realize a compact and more efficient absorber for Low temperature heat source. From those theoretical results, a prototype small absorption testing machine has been constructed, and the performances of the machine are checked now.

从节约化石燃料消耗和防止全球气候变暖的角度出发，微型分布式发电系统，即在大多数情况下的微型热电联产系统，受到了极大的关注。特别是聚合物电解质燃料电池（PEFC）被认为是最有前途的小型商用和民用发电系统，在PEFC热电联产系统中，电池堆的少量低温废热几乎都用来生产热水。因此，在研究中，首席研究员提出了一种新的空调余热利用方法。在建议的家庭热电联产系统中，吸收式制冷机已被引入，以产生冷冻水。为此，设计了一种新型的低浓度溶液循环，估算了其COP，并将其应用于数值模拟中，以开发一种高性能、紧凑型吸收器。对整个系统的性能和效率进行了定量预测，并与实际验证试验机进行了比较。此外，在过去的实验结果的基础上，新型垂直板式吸收器的性能预测已经进行，以找到新的技术，可以实现一个紧凑的，更有效的吸收器的低温热源。根据这些理论结果，已经建造了一个原型的小型吸收试验机，并检查机器的性能。
