Architecture Analysis, Modelling and Simulation of PEM Fuel Cell Systems for Aircraft Applications

Fuel cell systems are regarded to be a promising solution for future electrical energy generation on board of commercial aircrafts. In addition to an improved efficiency such systems offer the opportunity of producing water usable for on-board purposes and provide additional functions like inertization (providing a noninflammable atmosphere) of the jet fuel tank. We present an evaluation and assessment of different system architectures as well as experimental results under low pressure operation. Also complete system modeling is presented and the dynamic system behavior is analyzed.
