Fuel Cell Systems For Aircraft Application

Part of the flights are covered with fuel cell only energy systems while some of the.

Fuel cell systems for aircraft application. The antares dlr h2 which was remodeled from the antares 20e glider electric battery motor developed by dlr to study fuel cell technology for aircraft applications. This is demonstrated by combining the fuel cell model with simple and detailed design models of a liquid hydrogen tank. In that time we ve accumulated a great deal of knowledge across all technologies and sizes of different fuel cells. It can fly an entire flight phase using only fuel cell power independent of any hybrid operation or batteries.

However its climbing performance would be expected to improve with the addition of the hybrid system s power boost. Fuel cell systems are regarded as a promising solution for future electrical energy generation on board of commercial aircraft. Only with high specific energy batteries the degree of hybridization splits into two distinct values. Fuel cell sales design integration and consultancy.

The fuel cell needs to be designed in the context of the whole energy system. The team at fuel cell systems ltd has been applying fuel cells to real life tasks since 2003. This shows that with lower performing batteries hybridization is not beneficial and a fuel cell only system design should be used. The activities of dlr focus on identification of fuel cell applications in aircraft design and modeling of possible system designs experimental investigations regarding specific aircraft relevant operating conditions qualification of airworthy fuel cell systems and set up and full scale testing of fuel cell systems for applications in research aircrafts.
