直接甲醇燃料电池(DirectMethanolFuelCell,DMFC)是基于质子交换膜燃料电池发展而来的一种新型能量装置，具有甲醇来源丰富、价格便宜、燃料溶液容易储存和携带、电池的能量密度高、系统简单等优点，是各种中低功率便携式用电装置的理想替代动力源之一，因而成为现在燃料电池研究领域的热点之一。本文从燃料电池产业化的角度出发，对直接甲醇燃料电池的催化剂制备及其有关系统集成的核心技术进行了相关研究。在燃料电池催化剂的制备方面，本文首先综合考察了采用浸渍－液相还原法制备高担量燃料电池用Pt/C和PtRu/C催化剂的制备条件。实验发现，催化剂的颗粒大小与H2PtCl6的浓度关系不大。采用N2H...Direct methanol fuel cell (DMFC) has long been known as a useful energy-converting device via electrochemical reaction, which is modified from proton exchange membrane fuel cell (PEMFC). They were increasingly being considered for low to medium power applications due to the elimination of the fuel processor, light weight and small volume. Moreover, methanol as the fuel was considered to have seve...学位：理学博士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：B20022501
