This project builds upon two major results of priorr research to develop high performance Solid Oxide Fuel Cells (SOFCs) with improved durability and reliability using unique multilayered structural approach to design and process of electrolyte and cathode/anode constituents of the single cells. The first is the multilayered electrolytes with carefully designed thermal residual stresses bringing the significant increase in reliability of the electrolytes and the single cell as a whole, at the same time allowing maintaining the very high oxygen ion conductivity and chemical and phase stability of the structures. The second is the use of the catalytically active perovskites cathodes deposited by the superior additive manufacturing techniques on the electrolyte substrates. It is expected that highly compatible electrodes/electrolyte assemblies will be produced as single solid oxide fuel cells exhibiting superior power densities, reliability, and durability at lower operational temperatures. There is a growing global industry for fuel cells including, but not limited to: telecommunications; space industry; hospital and commercial building backup and; large-scale data backup. Fuel cells can potentially supply the total power demand for large capacity applications, while reducing carbon dioxide emissions. The SOFC systems developed through this project are quiet, have no carbon emissions and have the potential to reduce facility energy service costs. SOFCs can also be positioned on-site in remote areas, making it possible to match power generation to the electrical demands of the site.

该项目建立在先前研究的两个主要成果的基础上，利用独特的多层结构方法设计和处理单个电池的电解液和阴极/阳极组件，以开发具有更高耐用性和可靠性的高性能固体氧化物燃料电池(SOFC)。第一种是具有精心设计的热残余应力的多层电解液，大大提高了电解液和单电池的整体可靠性，同时保持了非常高的氧离子导电性以及结构的化学和相稳定性。第二种是在电解液衬底上使用由优越的添加剂制造技术沉积的具有催化活性的钙钛矿型阴极。预计高度兼容的电极/电解液组件将作为单一的固体氧化物燃料电池生产，在较低的工作温度下显示出优异的功率密度、可靠性和耐用性。全球燃料电池行业不断增长，包括但不限于：电信、航天工业、医院和商业建筑备份以及大规模数据备份。燃料电池有可能满足大容量应用的总电力需求，同时减少二氧化碳排放。通过该项目开发的SOFC系统安静、无碳排放，并有可能降低设施能源服务成本。SOFC也可以就地放置在偏远地区，从而使发电与现场的电力需求相匹配。
