Hybridized, High Pressure, Liquid Fueled Solid Oxide Fuel Cell (SOFC) for Aircraft Primary Power
2022 IEEE/AIAA TRANSPORTATION ELECTRIFICATION CONFERENCE AND ELECTRIC AIRCRAFT TECHNOLOGIES SYMPOSIUM (ITEC+EATS 2022)（2022）
Abstract
The primary focus of this paper was to examine the feasibility of using a solid oxide fuel cell (SOFC) generator (fueled with low sulfur liquid hydrocarbon) as the energy source for primary power of a small aircraft. Comparison with H 2 -fueled, low temperature proton exchange membrane (PEM) fuel cells was also examined. A complete set of hybridized generators (SOFC + turbine + battery) system layouts were developed for short and long duration flights. Solid models and packaging concepts for the optimized SOFC solutions for both mission durations were also developed based on our prior testing data on the sub-scale.The work resulted in identifying key risks for scalability to mega-watt (MW) scale electrified aircraft propulsion (EAP). It can also be used to support certification and regulations development for electrified aircraft propulsion (EAP) systems in future work.
