Shortly before the end of the FC_Bio project, the project committee met for its final meeting at the ZBT. The results from the four sub-projects were summarised. They should help to make fuel cells more environmentally friendly and sustainable than they already are.
Alternative propulsion systems are intended to make aviation more environmentally friendly. To achieve this, they need to be particularly light and powerful. A consortium with ZBT participation is currently developing a particularly power-dense fuel cell stack.
ZBT is developing air-cooled lightweight fuel cells with a high power density for research into an innovative, hydrogen-based drive system for UAVs and aircraft in the 25 kg to 2 tonne weight class.
Knowing the current water distribution in the fuel cell during operation is an important aspect in optimising the performance and service life of the fuel cell. In the new ‘US Fuel Cell’ project, ZBT and its partners are developing an innovative method based on ultrasonic waves.
Designing hydrogen refuelling systems for reliable and safe operation is a major challenge due to constantly changing requirements and rapid technological development. The HRS-Modell which has now been published, aims to help.
