Summary

Description

As solid oxide fuel cells (SOFCs) approach commercialization, interest in broader applications of this technology is mounting. While the first commercialized systems are being designed to provide 3-5 kW in stationary and automotive auxiliary power unit (APU) applications, aerospace and military users are considering integrating SOFCs into larger, airborne systems with considerable commercial payback. SOFCs are aligned to displace inefficient, noisy, and polluting technologies such as diesel generators that will provide both economic and environmental motivation to prospective users. NexTech Materials will develop a solid oxide fuel cells that demonstrate high power density, targeting 2W/cm2, a level of performance that will enable the compact, lightweight systems required for aerospace applications to become a reality. Such high power density SOFCs will provide the bridge from stationary residential power systems to airborne auxiliary power units. The fuel cells that result from these applications will lead the way to efficient and clean aircraft. This Phase I work will focus on processing and evaluating highly conductive electrolyte and electrode materials and the incorporation of these materials into high power density, SOFC cells suitable for commercial stack fabrication in Phase II.
