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.

In that time we ve accumulated a great deal of knowledge across all technologies and sizes of different fuel cells. Fuel cell aircraft specificities 1 3 fuel cell system location onto an aircraft thermal management waste heat from depleted air and cooling loop thermal power to evacuate depends on fcs electric performance stack design operational condition h2 purity temperature pressure design of cooling loop. However its climbing performance would be expected to improve with the addition of the hybrid system s power boost. Aircraft application do16xx functionality architecture bop fc system from transport application airworthy technology development platform fuel cell dc dc hydrogen storage fuel cell system efficiency as a function of cathode inlet pressure and relative humidity at the cathode outlet.

The team at fuel cell systems ltd has been applying fuel cells to real life tasks since 2003. Fuel cell systems are regarded as a promising solution for future electrical energy generation on board of commercial aircraft. Fuel cell sales design integration and consultancy. This is demonstrated by combining the fuel cell model with simple and detailed design models of a liquid hydrogen tank.

It can fly an entire flight phase using only fuel cell power independent of any hybrid operation or batteries. This conclusion is in accordance with the expectation that fuel cell systems are especially beneficial in terms of weight for long range aircraft kadyk et al 2018. This shows that with lower performing batteries hybridization is not beneficial and a fuel cell only system design should be used. Only with high specific energy batteries the degree of hybridization splits into two distinct values.

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. 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.
