Abstract:Current auxiliary power unit (APU) system in aircraft is heavy, noisy and inefficient, so a new form of power source to replace the engine mounted generator technologies is in demand. As a green power source, fuel cell is discussed in this paper to study the feasibility of the system as an APU. This paper investigates different fuel cell applications, and qualitative analysis shows that proton exchange membrane fuel cell (PEMFC) system performs the best. Then a PEMFC based APU system is proposed and designed theoretically. Comparisons between the new APU system and original one in B787 suggest that fuel cell based system performs better in the aspects of specific energy, specific power, efficiency, complexity and so on. With the development of the fuel cell stack, power electronics and hydrogen storage technologies, the fuel cell based APU is hopeful to be applied.
