The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to overcome a limiting step in creating viable hydrogen fuel cells for the automotive industry. The solution will renew the battery catalyst without its removal from the vehicle. This will result in significant savings toward the total cost of ownership and an increase in overall system reliability, one of the top features potential customers evaluate when making automotive purchasing decisions. The transportation industry has been seeking innovations to transition to sustainable solutions such as zero-emission and green hydrogen fuel cell technologies, but the broad adoption of such vehicles is limited by the short lifespan of fuel cell electrocatalysts that operate, expensive fuel cell stack replacements, and the high costs of components. This project will make hydrogen fuel cell vehicles viable and cost-competitive with diesel and gasoline engine vehicles by extending the lifetime of the electrocatalyst and thereby the fuel cell stack. Such alternative options are needed, as diesel vehicles are responsible for around 20% of anthropogenic pollution precursor emissions, and these emissions are linked to approximately 110,000 premature deaths per year.This SBIR Phase I project proposes to establish a proof-of-concept approach for in-stack platinum electrocatalyst renewal. Since fuel cell electrocatalysts degrade during operation, this project will develop a breakthrough technology that enables the reuse of what was once considered expended, end-of-life fuel cells by renewing the electrocatalyst. This renewal process can be conducted multiple times after the electrocatalyst inevitably degrades, increasing the lifetime and durability for fuel cell operation. As one of the most expensive precious metals, platinum typically used as the catalyst for automotive applications contributes to about 60% of the total fuel cell cost. This process is the first-in-kind to allow electrocatalyst renewal at the surface of the electrode without removing or replacing the fuel cell stack. This project will establish working parameters for the electrocatalyst renewal and analyze the effects of the process using a custom testing apparatus with a 3-electrode configuration and on commercial fuel cell membrane electrode assemblies in custom single-cell configurations. This team will utilize several techniques including analytical electrochemistry, microscopy, and electron paramagnetic resonance techniques to verify the effects of the process.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I期项目的更广泛的影响/商业潜力是克服为汽车行业创造可行的氢燃料电池的限制步骤。该溶液将续签电池催化剂，而无需将其从车辆中移除。这将为总拥有成本和总体系统可靠性提高带来可观的节省，这是潜在客户在做出汽车购买决策时评估的主要功能之一。运输行业一直在寻求创新，以过渡到可持续解决方案，例如零排放和绿色氢燃料电池技术，但是这种车辆的广泛采用受到运行，昂贵的燃料电池堆栈替换的燃料电池电催化剂的短期限制，以及组件的高成本。该项目将通过延长电催化剂的寿命，从而使燃料燃料电池汽车与柴油和汽油发动机车辆与柴油机和汽油发动机车辆相竞争，从而使燃料电池堆栈具有成本竞争力。需要这种替代选择，因为柴油车辆负责大约20％的人为污染前体排放量，并且这些排放量与每年约110,000个早期死亡有关。该SBIR I期项目提议建立一种验证验证的方法，以建立一种堆栈帕金尼姆电载体电动员Renewal。由于燃料电池电催化剂在操作过程中降低，因此该项目将开发一项突破性技术，该技术可以通过更新电催化剂来重新使用曾经被认为是消耗的东西，寿命终止燃料电池。 在电催化剂不可避免地降低后，可以多次进行此更新过程，从而增加了燃料电池运行的寿命和耐用性。作为最昂贵的贵金属之一，铂金通常用作汽车应用的催化剂，约占燃料电池总成本的60％。该过程是允许在电极表面更新电催化剂的第一个方法，而无需去除或更换燃料电池堆栈。该项目将建立用于续订电催化剂的工作参数，并使用具有3电极配置的自定义测试设备分析该过程的效果，以及在自定义单细胞配置中的商业燃料燃料电池电池电极组件。该团队将利用几种技术，包括分析电化学，显微镜和电子顺磁共振技术来验证该过程的影响。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来通过评估来支持的。
