Abstract

Fuel cell based auxiliary power units (APU) could be a good alternative to conventional, kerosene operated APUs. The eco efficiency could be enlarged by this technology. The dynamic characteristic of fuel cell systems necessitates an adaption of the electrical system. Using short time energy storage power delivery can be extended, demonstrated by a Matlab Simulink Simpower-Systems simulation with two scenarios. The first one is a 3 s storage for load step compensation. The second one is an exemplification of an electrical main engine start with energy storage. This could reduce the fuel cell weight. This paper compares three possible energy storage technologies to consider the requirements and it checks market availability.
