*** ABSTRACT 9661760 Pien This Small Business Innovation Research Phase I project will investigate a novel approach for preparing Pt electrocatalysts for proton exchange membrane (PEM) fuel cells. Platinum clusters will be impregnated inside carbonaceous structures protecting the active sites from poisonous gases such as CO, CO2, etc. At least two different impregnation techniques will be tested in Phase I including CVD deposition technique and impregnation from liquid phase. The carbonaceous materials will be chemically treated prior to impregnation by using oxidative treatment procedure. Prepared catalysts will be evaluated by cyclic voltammetry, X-ray spectroscopy, AUGER spectroscopy, and elemental analysis. The catalyst performance will be evaluated in a single fuel cell with 5 cm2 active area. Hydrogen and hydrogen with premixed CO will be used as reactant gases. A comparison between conventional Pt/Ru catalyst and the novel catalyst developed during Phase I will be performed. The catalyst developed during the proposed research program will have commercial applications in PEM fuel cells for transportation applications as well as for stationary fuel cell power systems operating on reformate gas and methanol. ***

*** 摘要 9661760 Pien 这个小型企业创新研究第一阶段项目将研究一种制备用于质子交换膜 (PEM) 燃料电池的 Pt 电催化剂的新方法。铂簇将被浸渍在碳质结构内，保护活性位点免受 CO、CO2 等有毒气体的影响。第一阶段将测试至少两种不同的浸渍技术，包括 CVD 沉积技术和液相浸渍。含碳材料在浸渍之前将使用氧化处理程序进行化学处理。制备的催化剂将通过循环伏安法、X射线光谱、俄歇光谱和元素分析进行​​评估。催化剂性能将在活性面积为 5 cm2 的单个燃料电池中进行评估。氢气和氢气与预混合的CO将用作反应气体。将进行传统 Pt/Ru 催化剂和第一阶段开发的新型催化剂之间的比较。 在拟议的研究计划中开发的催化剂将在运输应用的质子交换膜燃料电池以及使用重整气体和甲醇运行的固定燃料电池电力系统中具有商业应用。 ***
