熱化學產製氫氣被視為具效率方法之一，其中蒸氣重組反應已應用於產氫製程多年。實務上蒸氣重組製程所產製之氫氣產品氣，後續需經高壓純化分離程序，提純後之氫氣才能供應質子交換膜燃料電池發電使用。本篇文章主要描述以吸附助效技術導入蒸氣重組反應，單一步驟產製可供質子交換膜燃料電池使用之氫氣，探討其相關可行性。本研究以生質酒精為產氫料源，探討不同重組溫度、空間速度、反應壓力下對於產品氣組成影響。由實驗數據顯示，以雙功能鎳-鈣觸媒進行酒精蒸氣重組產氫反應，反應溫度低於500°C或操作壓力高於2 kg/cm²條件下，可獲得氫氣濃度大於95%、一氧化碳殘留低於1 ppmv以下之燃料電池等級氫氣。

Thermochemical hydrogen production is one of the efficient methods. The steam reforming reaction has been widely applied for several decades. In practice, the produced hydrogen by the steam reforming process needed to be purified through the high pressure separation process, and the purified hydrogen could be able to meet the request of proton exchange membrane fuel cell. The aim of this article is to investigate the production of hydrogen with fuel cell grade via one step process of sorption enhanced steam reforming of bioethanol reaction. The bi-functional nickel-calcium catalyst was employed to use in this work. Several factors involving temperature, space velocity and operation pressure were discussed, in order to evaluate the qualities of products for the steam reforming reaction. The result indicated that the hydrogen with fuel cell grade (> 95% H₂ and CO < 1 ppmv) could be obtained by one step process under the condition of temperature below 500 °C or pressure above 2 kg/cm².
