This Small Business Innovation Research (SBIR) Phase II project investigates the viability of an electrochemical device for separation and compression of hydrogen from low-pressure mixed gas streams that are critical for industrial gas and energy applications. Previous studies have shown that hydrogen derived from reformation of hydrocarbons produces a gas stream rich in CO2, CO and H2. It has been well- documented that low-temperature electrodes similar to those used in these devices are often contaminated by carbon monoxide, negatively affecting their operation. While state-of-the-art solutions rely upon implementation of advanced catalysts or high temperature membranes, these solutions are not viable for systems having significant levels of CO in the feed stream. Specifically the project will focus on solving electrode contamination issues through a series of design modifications; allowing the system to operate continually at high efficiency. Research efforts will leverage results from a fluids transport model to optimize the cell and system design. Laboratory cells will be constructed and evaluated over a range of operational parameters to develop a better understanding of the performance improvement associated with this approach. This program will culminate in the construction of a fully-integrated system package that will be tested and validated with real-world reformate chemistries.The broader impact/commercial potential of this project relates to the fact that depletion of fossil fuel reserves and a global requirement for the development of a sustainable economy, the prospect of hydrogen-based energy is of growing importance. Production, purification and compression of hydrogen represent key technical challenges for the implementation of a hydrogen economy, especially in the transportation sector where new sources and modes of delivery of hydrogen are needed. These technologies must be robust, efficient, and cost effective in order to have value in meeting our energy needs. Since hydrogen energy markets are emerging, viable product solutions must meet near-term industrial needs as a commercial bridge toward low-cost energy products. The current market for hydrogen is large and growing, with the vast majority of hydrogen produced from hydrocarbon sources resulting in gas streams containing appreciable quantities of CO and CO2 and hydrogen. Current methods for separation and compression of hydrogen are very expensive and these costs are passed to the end-user. Successful development of the proposed technology will integrate the separation and compression functions, and expand the applicability of this device to separation of reformate and other mixed gas streams in a low-cost configuration which offers significant commercial appeal.

该小型企业创新研究(SBIR)第二阶段项目研究了用于从对工业气体和能源应用至关重要的低压混合气流中分离和压缩氢气的电化学设备的可行性。以前的研究表明，烃类重整产生的氢气会产生富含二氧化碳、一氧化碳和氢气的气流。与这些装置中使用的低温电极类似的低温电极经常受到一氧化碳的污染，对其运行产生了不利影响，这一点已经得到了充分的证明。虽然最先进的解决方案依赖于先进催化剂或高温膜的实施，但这些解决方案对于进料流中CO含量较高的系统是不可行的。具体地说，该项目将专注于通过一系列设计修改解决电极污染问题，使系统能够以高效率持续运行。研究工作将利用流体传输模型的结果来优化电池和系统设计。实验室单元将根据一系列操作参数进行构建和评估，以更好地了解与此方法相关的性能改进。该计划最终将构建一个完全集成的系统包，并将用真实世界的重整化学家进行测试和验证。该项目更广泛的影响/商业潜力涉及到这样一个事实，即化石燃料储备的枯竭和全球对可持续经济发展的需求，氢基能源的前景越来越重要。氢气的生产、提纯和压缩是实施氢经济的关键技术挑战，特别是在需要新的氢气来源和输送方式的运输部门。这些技术必须是强大、高效和具有成本效益的，才能在满足我们的能源需求方面具有价值。由于氢能市场正在兴起，可行的产品解决方案必须满足近期的工业需求，作为通向低成本能源产品的商业桥梁。目前氢的市场很大，而且还在不断增长，绝大多数氢都是从碳氢化合物来源产生的，导致气流中含有相当数量的CO、CO2和氢。目前分离和压缩氢的方法非常昂贵，这些成本被转嫁给最终用户。该技术的成功开发将集分离和压缩功能于一体，并将该装置的适用性扩大到以低成本配置分离重整油和其他混合气流，具有重大的商业吸引力。
