The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to make on-site hydrogen generation convenient and economically viable. Hydrogen is a chemical used widely in industry and serves an alternative fuel source for electric vehicles, increasing drive range and shortening refueling time, but adoption has been limited by the needs for refueling infrastructure. One method to address this is to create hydrogen by splitting water, alleviating the safety, logistical, and reliability issues associated with the delivery and storage of hydrogen, but existing technology has been associated with high capital and operating costs. The objective of this proposal is to advance water splitting technology, enabling a non-polluting, zero-emission hydrogen solution.This Small Business Innovation Research (SBIR) Phase II project will develop an advanced electrolyzer. The project will (1) synthesize the catalysts and fabricate these electrodes on an industrial scale; (2) characterize the relationship between electrode architecture and kinetic and mass-transfer limitations; and (3) identify the electrode architecture, stack compression, and flow rates required to translate the performance of these electrodes to an industrial-sized prototype. The project will utilize mathematical modeling to guide electrode architecture development and a three cell industrial-sized test stack for experimental testing before employing electrodes in a full 4 kg/day stack. Furthermore, the project will employ the electrodes in a 4 kg/day pressurized stack and integrate these components to produce hydrogen at 20 bar to the SAE J2719 standard of 99.998% purity. The projected targets for stack and system efficiency for the final system are 43 kWh/kg and 55 kWh/kg.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.

这个小型企业创新研究(SBIR)第二阶段项目的更广泛的影响/商业潜力是使现场制氢变得方便和经济可行。氢气是一种在工业上广泛使用的化学品，可以作为电动汽车的替代燃料来源，增加续航里程，缩短加油时间，但由于对加油基础设施的需求，氢的采用一直受到限制。解决这一问题的一种方法是通过裂解水来产生氢气，缓解了与氢气输送和存储相关的安全、后勤和可靠性问题，但现有技术一直与高昂的资本和运营成本相关。这项提议的目标是推进分水技术，实现无污染、零排放的氢气解决方案。这个小型企业创新研究(SBIR)第二阶段项目将开发一种先进的电解槽。该项目将(1)合成催化剂并在工业规模上制造这些电极；(2)表征电极结构与动力学和传质限制之间的关系；(3)确定将这些电极的性能转化为工业规模原型所需的电极结构、堆叠压缩和流速。该项目将利用数学建模来指导电极结构的开发，并在将电极全部用于每天4公斤的电堆之前，使用一个三电池工业尺寸的测试电堆进行实验测试。此外，该项目将采用4公斤/天的加压电堆中的电极，并将这些组件集成到20bar，以符合99.998%纯度的SAE J2719标准。最终系统的堆叠和系统效率的预测目标是43千瓦时/公斤和55千瓦时/千克。这一奖励反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
