*** ABSTRACT 9661134 Murphy This Small Business Innovation Research Phase I project will demonstrate the feasibility of using conducting polymers to fabricate bipolar plates for proton exchange membrane (PEM) fuel cells. To make PEM fuel cell power sources for electric vehicles cost-competitive with competing technologies, materials cheaper than presently used carbon/resin composites for bipolar plates must be identified and more cost-effective methods of manufacturing these plates compared to high temperature graphitization of carbon/resin composites must be developed. The goal of this project is to take advantage of recently developed electronically conducting polymer technology for the development of superior and cost effective bipolar plates for PEM fuel cell stacks compared to the conventionally used graphitized carbon-based materials. The aim is to electrochemically synthesize net shape, high strength conducting polymer structures that exhibit high electronic conductivity at elevated temperatures in the presence of oxygen and that are not subject to oxidation/corrosion processes in oxygen-saturated acidic environments at elevated temperatures. The attractiveness of the approach is that it will allow the room temperature preparation of high strength, highly conducting polymer materials suitable for use not only as bipolar plates in PEM fuel cell stacks but also in other acid fuel cell systems, such as the phosphoric acid fuel cell (PAFC) system. Thus, developed technology arising from this project should be an enabling technology leading to the manufacture of low cost fuel cell stacks. Low temperature methanol/air and hydrogen/air PEM fuel cells have considerable commercial potential as power sources for electric vehicles. Other commercial applications include: electricity and heat production for residential and small commercial buildings; portable power sources for communications and news gathering equipment; portable medical instrumentation used by rescue teams; and external electrical power sources for artificial heart and ventricular-assist devices. ***

* 摘要 小行星9661134 这个小企业创新研究第一阶段项目将证明使用导电聚合物制造质子交换膜（PEM）燃料电池双极板的可行性。为了使用于电动车辆的PEM燃料电池电源与竞争技术相比具有成本竞争力，必须确定比目前用于双极板的碳/树脂复合材料更便宜的材料，并且必须开发与碳/树脂复合材料的高温石墨化相比更具有成本效益的制造这些板的方法。该项目的目标是利用最近开发的电子导电聚合物技术，与常规使用的石墨化碳基材料相比，开发用于PEM燃料电池堆的上级和成本有效的双极板。目的是电化学合成网状、高强度导电聚合物结构，其在氧存在下在高温下表现出高电子电导率，并且在高温下在氧饱和的酸性环境中不经受氧化/腐蚀过程。该方法的吸引力在于，它将允许在室温下制备高强度、高导电性的聚合物材料，其不仅适用于PEM燃料电池堆中的双极板，而且适用于其他酸性燃料电池系统，例如磷酸燃料电池（PAFC）系统。因此，从这个项目中产生的开发技术应该是一个使能技术，导致低成本燃料电池堆的制造。 低温甲醇/空气和氢/空气PEM燃料电池作为电动汽车的电源具有相当大的商业潜力。 其他商业应用包括：住宅和小型商业建筑的电力和热力生产;通信和新闻采集设备的便携式电源;救援队使用的便携式医疗仪器;以及人工心脏和心室辅助装置的外部电源。***
