SBIR Phase II: Advanced alkaline electrolyzer stack for hydrogen peroxide onsite production

这个小型企业创新研究(SBIR)项目的更广泛影响/商业潜力是过氧化氢生产方面的重大进步。预计该项目将产生一种现场产生方法，与传统的集中式化学工艺相比，这种方法大大降低了过氧化氢的生产成本。通过降低成本，过氧化氢可以更广泛地用作漂白、饮用水和废水处理等过程中的氧化剂，最终通过取代氯基氧化剂来降低氯污染。纸浆/造纸和纺织业将受益于成本更低的漂白剂和更低的处理成本。该方法减少了环境污染，并消除了运输爆炸性高浓度过氧化氢的需要。新的设计可能会在其他工业系统中应用。这个SBIR二期项目旨在展示一个放大的高效碱性过氧化氢电解槽系统。最终结果将是一个可用于商业演示的原型。电极制造工艺将进行优化，以适应卷材到卷材涂覆生产线的大批量生产。电解槽原型将被建造并在中等规模上进行测试，具有中等细胞数量，然后改进并扩大到具有高细胞数量的全尺寸细胞。将进行耐久性测试，包括制定加速测试协议，以促进电极材料的筛选和评估在卷材到卷材涂层中实施的制造差异。这些单独的项目目标将最终形成用于现场产生过氧化氢的商业试点自主系统。该奖项反映了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。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is a significant advance in the production of hydrogen peroxide. It is anticipated that this project will yield an on-site generation method that substantially reduces the cost of peroxide production compared to the traditional centralized chemical process. By reducing cost, hydrogen peroxide can be used more widely as an oxidizer in bleaching, drinking water and wastewater treatment, and other processes, ultimately lowering chlorine pollution by replacing chlorine-based oxidizers. The pulp/paper and textiles industry will benefit from lower cost bleaching chemicals and reduced treatment costs. This method reduces environmental pollution and eliminates the need for transportation of explosive high-concentration hydrogen peroxide. The new design may have applications in other industrial systems.This SBIR Phase II project proposes to demonstrate a scaled-up high efficiency alkaline hydrogen peroxide electrolyzer system. The end result will be a commercial demonstration-ready prototype. The electrode manufacturing process will be optimized for high-volume manufacturing on roll-to-roll coating lines. Electrolyzer prototypes will be built and tested at medium scale with a moderate cell count, then improved and scaled to full-size cells with a high cell count. Durability testing will be performed, including development of accelerated testing protocols, to facilitate screening of electrode materials and assess manufacturing variations implemented in roll-to-roll coating. These individual project goals will culminate in a commercial pilot-ready autonomous system for on-site generation of hydrogen peroxide.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.
