The Small Business Innovation Research (SBIR) Phase I project will develop a novel, Dimensionally Stable Ionomer Membrane (DSMTM) that offers high ionic conductivity, good ion exclusion capability, and excellent mechanical properties. The most advanced chlor-alkali electrolyzers utilize an ion-exchange membrane to separate the electrolysis solutions, but that membrane introduces inefficiencies due to the thickness required to survive and function within the electrolyzer. This research project deals with a new type of membrane utilizing a thin, laser-perforated support and incorporating carboxylic and sulfonic acid ionomers to simultaneously reduce the thickness of the membrane (and therefore the electrolyzer operating voltage) while maintaining functionality and improving durability. Just a few years ago, chlor-alkali electrolysis consumed 1.4% of all electricity generated in the United States; thus any improvement to electrolysis efficiency would result in significant power savings. The proposed research is expected to result in an electrolyzer voltage reduction of at least 125mV of the ~3.0V currently consumed, an energy consumption reduction of 4.2%.

小企业创新研究（SBIR）第一阶段项目将开发一种新型的、表面稳定的离子交换膜（DSM TM），该膜具有高离子电导率、良好的离子排斥能力和优异的机械性能。最先进的氯碱电解槽利用离子交换膜来分离电解溶液，但是由于在电解槽内存活和起作用所需的厚度，该膜引入了低效率。 该研究项目涉及一种新型膜，该膜利用薄的激光穿孔支撑并结合羧酸和磺酸离聚物，以同时降低膜的厚度（从而降低电解槽的工作电压），同时保持功能性并提高耐用性。 就在几年前，氯碱电解消耗了美国所有发电量的1.4%;因此，电解效率的任何提高都将导致显着的节能。拟议的研究预计将导致电解槽电压降低至少125 mV的约3.0V目前消耗，能源消耗减少4.2%。
