SBIR Phase I: Development of Molecular-Sieve Electrocatalysts for Proton Exchange Membrane (PEM) Fuel Cells

*9661760 Pien这个小型企业创新研究第一阶段项目将探索一种制备质子交换膜燃料电池用铂电催化剂的新方法。铂团簇将被浸渍在碳结构中，以保护活性中心免受CO、CO2等有毒气体的影响。在第一阶段将测试至少两种不同的浸渍技术，包括CVD沉积技术和从液体浸渍。碳质材料在浸渍前将通过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、X射线光谱、俄歇光谱和元素分析进行评估。催化剂的性能将在活性面积为5cm2的单一燃料电池中进行评估。氢气和带有预混CO的氢气将被用作反应气体。对传统的铂/Ru催化剂和第一阶段开发的新型催化剂进行了比较。在拟议的研究计划期间开发的催化剂将在PEM燃料电池中进行商业应用，用于运输应用，以及使用重整气和甲醇的固定式燃料电池动力系统。***

*** 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. ***
