雙級熱壓縮儲氫系統模組建立及性能參數研究

Abstract

氫氣儲存及輸送過程上之安全性偏低，故在氫氣使用時，如何儲存加壓是目前面臨難題之一。在本文中使用儲氫合金材的特性，解決此類問題。儲氫合金材的體積儲存密度高且穩定性佳，而不同的溫度可使氫氣在儲氫合金材的吸氫壓力、放氫壓力特性滿足在壓縮轉換過程中所需的機制。本文討論使用熱源將不同之儲氫合金粉末特性改變，將多段壓縮氫氣，此方法相較於一般機械式氫氣壓縮機所需的耗能少，且安全性及穩定性都較好。 本研究經過多年對儲氫合金的研發，及研究其相關之參考文獻，發展出熱壓縮儲氫系統；說明儲氫合金特性及系統設計，此系統為熱驅動且無傳動元件的氫氣壓縮機。並討論氫氣壓縮系統隨著不同的入口壓力、不同冷熱源的轉換時間及熱交換之設計，所產生的最佳效益及結果。

The safety of hydrogen storage and transformed efficiency is inferior. The main problem is how to store hydrogen and compressor the pressure to while supplying to the fuel cell. The hydrogen metal is put to use to remove the drawback. The character of metal hydride is high volumetric density in safe and reliable hydrogen storage, and we can get specific pressure in need of transformation by exchange environmental temperature. Compared to the traditional mechanical hydrogen compressor, compressing several sorts of heated hydrogen metal in more effective, and it is also safe and steady. “Thermal Hydride Compressor System.”, which is the hydride compressor that perform by heat and need not transmission. To find the best operation efficiency in controlling difference inlet-pressure, the time of heat-exchange and heat-exchange chamber. This paper will also refer to the system-design and introduction of metal hydride.
