Fuel cells and the hydrogen energy pathway can lead to significant societal benefits, improving the quality of life, health and the environment. Fuel cells are already being used in a number of early market applications (e.g., materials handling, uninterrupted power supply, residential co-generation, personal device applications, etc) with many other applications at the advanced demonstration stage. Improvements in PEM fuel cell performance will require new design concepts for creation of an efficient catalyst layer. This project is focused on the manufacturing of thin metal catalyst layers on polymer electrolyte membranes using an electroless plating method in conjunction with different templating techniques. The main benefit of this project is the development of a cost effective method to fabricate highly active catalyst-coated membranes (CCMs) for PEM fuel cells. Cost reduction is one crucial aspect of PEM fuel cell manufacturing in addition to the creation of a highly active CCM. This project proposes a simple approach towards the creation of low loading highly active catalyst layer that will result in improved batch to batch reproducibility also providing an entrance point for the development of high volume manufacturing procedures.

燃料电池和氢能途径可以带来显著的社会效益，改善生活质量、健康和环境。燃料电池已被用于许多早期市场应用(例如，材料处理、不间断电源、住宅热电联产、个人设备应用等)以及许多其他处于高级示范阶段的应用。PEM燃料电池性能的提高将需要新的设计理念来创建高效的催化剂层。本项目的重点是使用化学镀方法结合不同的模板技术在聚合物电解质膜上制造薄金属催化层。该项目的主要好处是开发了一种成本效益高的方法来制备用于PEM燃料电池的高活性催化剂涂层膜(CCM)。除了制造高活性的CCM之外，降低成本是PEM燃料电池制造的一个关键方面。该项目提出了一种创建低装载量高活性催化剂层的简单方法，这将提高批次到批次的重现性，也为大批量制造程序的开发提供了一个切入点。
