Titel:

Assessment of a Fuel Cell Powered Full Electric Subsystem Architecture for the Avacon Research Baseline Aircraft

Autor(en): J. van Wensveen, F. Peter, T. Rau, M. Hornung
Zusammenfassung: This paper presents work from the research project AVACON on subsystem design and analysis: a first potential assessment of a polymer electrolyte membrane fuel cell powering a full electric subsystem architecture and replacing the conventional auxiliary power unit. The electrical subsystems power load calculations and the component sizing of the fuel cell system are performed with a mix of statistical, semi-empirical, and semi-analytical methods within the tool eFLOWpy. A 2% operational empty mass increase is assumed to account for the subsystem electrification mass change. The fuel cell system considered consists of six fuel cell stacks, a liquid hydrogen storage tank, a compressor to provide cabin air and a cooling loop with heat exchanger. The mass and volume of the fuel cell system is calculated on a main component basis. The overall sizing and analysis considers a standard mission trajectory including diversion. The results show a kerosene block fuel reduction of 1.2% compared to the AVACON research baseline aircraft with conventional subsystems, while further fuel cell system optimisation could potentially lead to a 3% reduction.
