This Small Business Innovation Research Phase I project will demonstrate the feasibility of designing engineered mesoporous zirconia films for intermediate temperature (600°C) solid-oxide fuel cells (IT-SOFCs) with the aim of extending the basic and practical knowledge of synthesis as well as electronic behavior of mesoporous films, while at the same time producing materials that have a direct application in IT-SOFCs. This work will, for the first time, demonstrate mesoporous zirconia films for IT-SOFCs. The objectives of this study are: 1) refinement and detailed design of a large-scale and practical means of generating significant amounts of mesoporous zirconia powders and films, and 2) assessment of the ionic conductivity properties of the films. The successful completion of this project will result in mesoporous ceramic films with high electronic conductivity for IT-SOFCs. Compared to state-of-the-art, the proposed technology has competitive advantages including: synthesizing highly stable mesoporous materials, obtaining compacts with grain sizes in the nanometer regime, and allowing the determination of permeability and electronic properties in these types of materials.The broader impacts/commercial potential of this project is to aid in the development of less expensive fuel cells. This technology could provide a solution for portable power and partly eliminate the need for batteries. SOFCs offer a promising technology options for the fuel cell industry which is one of the fastest growing segments of the power industry due to the need for reliable power sources. Most SOFCs are used at the operating temperature of 800-1000°C because the resistance of the standard commercial electrolyte material is lower at high operating temperatures. To reduce the cost of the SOFCs and to accelerate their market application, the operating temperature of SOFCs needs to be decreased. Mesoporous zirconia is an excellent candidate material for the IT-SOFCs application. The mesoporous film technology is unique compared to the competing technology and will allow for the development of effective power sources. This technology is of increasing importance for the future energy needs of this country.

这个小型企业创新研究阶段I项目将证明设计工程的介孔锆膜用于中等温度（600°C）固体氧化物燃料电池（IT-SOFC），目的是扩展基本的和实践的同步知识，同时在同一时间上构成了媒介材料的同时构成材料的同时构成iTCOF的同时构成材料。这项工作将首次展示IT-SOFC的介孔锆电影。这项研究的目标是：1）大规模和实用方法的细化和详细设计，用于产生大量的中孔锆粉和膜，以及2）评估膜的离子电导率。该项目的成功完成将导致IT-SOFC具有高电子电导率的介孔陶瓷膜。与最先进的技术相比，提出的技术具有竞争优势，包括：合成稳定的介孔材料，在纳米机制中获得带有晶粒尺寸的紧凑型，并允许确定这些类型的材料中的渗透性和电子特性。该项目的更广泛的影响/商业潜力是有助于开发较便宜的燃料电池。该技术可以为便携式功率提供解决方案，并部分消除了对电池的需求。 SOFC为燃料电池行业提供了有希望的技术选择，这是电力行业增长最快的部分之一，因为需要可靠的电源。大多数SOFC在800-1000°C的工作温度下使用，因为标准商用电解质材料的电阻在高工作温度下较低。为了降低SOFC的成本并加速其市场应用，需要提高SOFC的工作温度。介孔锆石是IT-SOFCS应用的出色候选材料。与竞争技术相比，介孔膜技术是独一无二的，它将允许开发有效的电源。这项技术对这个国家的未来能源需求越来越重要。
