氫能直接驅動型SOFC燃料電池排熱再利用吸收式空調系統效益評估
Performance Evaluation of Direct-Driven Hydrogen Energy SOFC Using Exhaust Heat of Absorption Heat Pump Systems
摘要
由於目前新興工業國高科技發展迅速，所需能源消耗越來越多，為減低地球暖化效應，呼應減碳節能的環保趨勢升高，故許多先進國提出高效率低污染的替代能源來取代石油做使用，其中以燃料電池應用在發電上最受矚目，因高溫型燃料電池具有高發電量、高效率等主要特性。 各式不同類型之燃料電池中，以固態氧化物燃料電池目前已越來越受到關注，未來其容量設計將會越來越大（目前為200~500kw）。本文探討以氫氣為直接燃料供應不同之固態氧化物燃料電池系統，在燃料供應下之SOFC型燃料電池，利用搭配吸收式熱泵(Absorption Heat Pump, AHP)之各項性能效益，期能提供不同串聯應用情況時有利設計上之參考。另針對使用氫氣燃料之固態氧化物燃料電池系統，其系統效率和操作參數，可用於典型的住宅大樓之效益分析，並嘗試利用該系統的性能差異來比較，並依熱力學第一及第二定律為氫氣分析其系統效率及燃料電池發電效率，最後比較總結評論相關應用的技術。

As the current rapid development of new high-tech industrial countries, more and more energy consumption required for reducing the global warming effect, echoing the trend of environmental protection by increasing carbon energy, so many advanced countries make high-efficiency low-pollution alternative energy to replace oil make use, in which fuel cells used in power generation of the most attention, because of high temperature fuel cell with high capacity, high efficiency and other main features. This study examines the direct hydrogen fuel supply for the different solid oxide fuel cell system, fuel supply, the SOFC type fuel cell, the use of absorption heat pump with the performance benefits, provide different series of applications enabling the design of the time reference. Another use of hydrogen fuel for solid oxide fuel cell system, the system efficiency and operation parameters can be used for residential buildings is a typical benefit analysis, and try to use the system to compare the performance difference, and according to the first and second laws of thermodynamics analyze the efficiency of the system for the hydrogen and fuel cell power generation efficiency, and finally compare the application of technologies related to the concluding comments.
