摘要

近年來，利用鋁金屬在水中水解可得到一種乾淨又環保的產氫方法，並且在工業領域當中廣泛的備受關注以及利用，以及燃料電池的興起，對於產氫就更加的重視，然而在整個產氫過程中，產氫效率以及產氫量是很重要的考量因素。因此在本文中，利用鋁粉末添加鎳金屬與鉍金屬粉末以及鋁箔並且在不同溫度的情形下進行產氫反應，混合了不同濃度的PH值，藉以改善產氫之效能與效率，希望可以應用於燃料電池方面。添加氫氧化鈉溶液是一個簡單又有效促進鋁與水的反應，但是過多的氫氧化鈉溶液會造成環境的破壞與儀器的腐蝕，所以我們利用了鎳與鉍來增加了產氫的效果，可以很明顯的提高產氫效率與產氫效果並在不同的溫度環境下，進而減少使用氫氧化鈉的溶液。再利用廢物回收的鋁箔進行產氫，提高反應時的溫度進而取代氫氧化鈉濃度的使用，以達到資源回收以及減少環境的破壞。此外，未了更加深入的探討鋁表面氧化的情形，使用了氧化成長動力論-線性拋物線模型研究鋁水反應表面生成的機制，藉此希望可以利用鋁水產氫的方法，找出一種最好的產氫方式，並應用於燃料電池，達成循環的概念。

In recent year, it can obtain a clean fashion and environment of hydrogen production method by using aluminum in the hydrolysis of water and it is concerned and used in the industry. It is more concern on hydrogen production of the fuel rise. In the process of hydrogen production, it is important of hydrogen production rate and yield. In this work, we use aluminum powder add nickel metal and add bismuth metal powder of hydrogen generation react in the case of different temperatures with mixing different concentrations of pH value with improvement the effectiveness and efficiency of hydrogen generation. We hope it can be applied on fuel cells. It is a simple and effective to promote the reaction of aluminum with water by adding NaOH. However, the use of NaOH causes problems with corrosion of system apparatus, so we use the nickel and the bismuth to increase the effectiveness of hydrogen generation, it can be improved hydrogen generation and hydrogen effectiveness signification at different temperature, therefore it can reduce the use of NaOH. The linear-parabolic law is introduced to explain Al oxidation mechanism .In addition we hope to find the best hydrogen generation and apply on the fuel cell to achieve the cycles.
