DESCRIPTION (provided by applicant): The long term objective is to enable greater mobility and quality of life for patients who require ventricular assist devices. The approach is to develop direct methanol fuel cell (DMFC) technology that will provide power for much longer periods at a fraction the weight of batteries. DMFC technology promises an order of magnitude reduction in the weight of the power source, which would enable a much greater quality of life for heart assist device (HAD) patients. The specific aims of Phase I are to develop stack technology that is very lightweight and advanced membrane/electrode assemblies (MEAs) that provide efficient and reliable long-term operation. The Phase I research plan calls for design and fabrication of stack components, development and testing of new catalyst formulations and MEA fabrication approaches, and integration of the MEAs with the stack components to demonstrate the performance of a complete fuel cell stack. Finally, data from Phase I testing will be used as the basis for the design of a complete power system, demonstrating the potential for very high energy density. The potential for technological innovation is high, because the program focuses on the key challenges that will enable more widespread use of DMFC technology.

描述（由申请人提供）： 长期目标是为需要心室辅助装置的患者提供更大的活动能力和生活质量。该方法旨在开发直接甲醇燃料电池（DMFC）技术，该技术能够以电池重量的一小部分提供更长的供电时间。 DMFC 技术有望将电源的重量减轻一个数量级，从而提高心脏辅助装置 (HAD) 患者的生活质量。第一阶段的具体目标是开发非常轻量且先进的膜/电极组件（MEA）的堆栈技术，以提供高效且可靠的长期运行。第一阶段研究计划要求设计和制造电池堆组件、开发和测试新的催化剂配方和 MEA 制造方法，以及将 MEA 与电池堆组件集成，以展示完整燃料电池堆的性能。最后，第一阶段测试的数据将用作完整电力系统设计的基础，展示极高能量密度的潜力。技术创新的潜力很大，因为该计划重点关注使 DMFC 技术得到更广泛应用的关键挑战。
