This Small Business Innovation Research (SBIR) Phase I project will develop a low-cost composite proton exchange membrane (PEM) capable of high temperature operation (150 degrees C) with excellent chemical resistance and good thermal and dimensional stability suitable for advanced fuel cells in next generation vehicles (NGV). The key to this new composite membrane is a high temperature, high strength, chemically resistant membrane support structure fabricated from Foster-Miller's patented porous single crystal alumina material. Tailored porosity structures have been fabricated with interconnected passages suitablefor infusion with a suitable ion conducting polymer (ICP) for high strength PEM's. This new PEM will address the serious cost/performance problems associated with current perfluorinated membranes. Fuel cells based on this new technology will achieve power density greater than 0.2 W/cm2. Membrane cost should eventually approach the $80/m2 level necessary to promote development of the NGV. Commercial scale up of the porous single crystal alumina manufacturing is already underway with a commercial processor of ceramics. During Phase I small composite Membrane Electrode Assemblies (MEA's) will befabricated, characterized and electrically tested for high temperature conditions (150 degrees C) and peroxide stability. Phase II will optimize the composite PEM with fabrication and testing of MEA fuel cell stacks.Commercial applications for the proposed advanced composite PEM include cost efficient fuel cells for automotive, utility and space/military applications. As a potentially key enabling technology for the automotive (NGV) application, the market potential is very large. Utility uses include communications, computers (laptop) and remote power generation. Space and military include manned space missions (space station), shipboard power, battery replacements and portable/mobile field generating units.

该小型企业创新研究（SBIR）第一阶段项目将开发一种低成本的复合质子交换膜（PEM），能够在高温（150摄氏度）下运行，具有优异的耐化学性和良好的热稳定性和尺寸稳定性，适用于下一代汽车（NGV）中的先进燃料电池。 这种新型复合膜的关键是一种高温、高强度、耐化学腐蚀的膜支撑结构，由Foster-Miller的专利多孔单晶氧化铝材料制成。 定制的多孔结构已经被制造成具有适于注入合适的离子传导聚合物（ICP）的互连通道，用于高强度PEM。 这种新的质子交换膜将解决与目前全氟膜相关的严重成本/性能问题。 基于这项新技术的燃料电池将实现大于0.2 W/cm 2的功率密度。 膜成本最终应接近促进天然气汽车发展所需的80美元/m2水平。多孔单晶氧化铝生产的商业规模已经在用陶瓷的商业处理器进行。 在第一阶段，小型复合膜电极组件（MEA）将被制造，表征和高温条件（150摄氏度）和过氧化物稳定性的电气测试。第二阶段将通过MEA燃料电池堆的制造和测试来优化复合材料PEM。所提出的先进复合材料PEM的商业应用包括汽车、公用事业和空间/军事应用的成本效益高的燃料电池。作为汽车（NGV）应用的潜在关键技术，市场潜力非常大。公用事业用途包括通信、计算机（笔记本电脑）和远程发电。航天和军事包括载人航天任务（空间站）、船上电源、电池更换和便携式/移动的发电机组。
