This Small Business Technology Transfer (STTR) Phase I project will develop a method for improving the transmembrane conductivity of Nafion. This project proposes to develop a method for modifying the orientation of the conductive channels though which ions traverse in ionomer membranes. Shear forces that occur during membrane manufacture tend to cause orientation of the channels in a direction parallel to the membrane surface. The proposed modification to the membrane manufacturing process would orient these channels in a direction perpendicular to the membrane, and that preferred orientation would result in higher transmembrane transport. The proposed research will have a direct impact on variety of applications in which directional transport is essential. Specifically, this modification method would allow the manufacture of ionomer membranes with improved ionic conductivity in the direction that is most beneficial to reduction of power consumption in electrolyzers (utilized in the manufacture of chlorine and caustic and in the production of hydrogen) and increase in the power output of PEM fuel cells.

这个小型企业技术转移（STTR）I期项目将开发一种改善Nafion跨膜电导率的方法。该项目建议开发一种修改导电通道方向的方法，尽管哪个离子在离子体膜中遍历。在膜制造过程中发生的剪切力倾向于在平行于膜表面的方向上引起通道的取向。提出的对膜制造过程的修改将使这些通道朝着垂直于膜的方向定向，并且优选方向将导致较高的跨膜运输。拟议的研究将对定向运输至关重要的多种应用产生直接影响。具体而言，这种修饰方法将允许生产离子膜的离子电导率提高的方向，这对于减少电解剂的功耗（用于生产氯和苛性氢以及氢的生产）并增加了PEM燃料电池的功率输出的增加。
