凝胶固相法合成MCFC隔膜材料α-LiAlO_2及其特性分析
|
摘要
熔融碳酸盐燃料电池技术已经进入了商业化的前期,成本问题是制约其商业化的因素之一。文中采用凝胶固相法制备的α-LiAlO2粉末材料粒径及纯度与"氯化物法"基本相当,但是制备过程大大简化,制备成本大大降低,并对其固相反应过程进行了分析,指出其反应机制为"吸入机制"。所以,采用凝胶固相法制备α-LiAlO2粉末材料是一种简单,环保,低成本的制备方法。
Molten carbonate fuel cell(MCFC)technology has entered the initial stage of commercialization, but the cost problem limited the development of MCFC. The α-LiAlO2 powder was prepared by gel-solid method. Moreover, the purity and particle-distribution were analyzed, and the results present that the purity and particle-distribution are similar to the powder prepared by "Chloride" synthesis method. However, the gel-solid method is very simple compared to "chloride" synthesis method, which could reduce the cost of the preparation of α-LiAlO2 powder. In addition, the reaction mechanism was analyzed and the reaction was considered to proceed by "imbibition mechanism". Therefore, the gel-solid method is one kind of simple, green and low-cost method.
