Our competitor for the Shell Eco-Marathon 2022

After our founders had spent a long time gathering funds and designing an efficient fuel cell system, we went to our debut Shell Eco Marathon to compete with Charlemagne against other universities in the Urban Concept Category.

In this category the car has to have certain features like lights, wiper, horn and a storage compartment while being as efficient as possible on the track.

Vehicle highlights

Aeroshell and chassis

For our first attempt at an aeroshell we focused on ease of manufacturing. Therefore, we started with a handcrafted Styrofoam and wood mould, on top of which is carbon fibre lay-up with infusion.

We have a simple ground plate design: structural base with an angled wall for stability between the driver compartment and the fuel-cell compartment, all made out foam core carbon fiber sandwich. For simplicity and lightweightedness, dampers were omitted.

Electrical and fuelcell system

The power supplied for driving and our main system comes from a 3 kW fuel cell system. This power is supplied to the DC/DCs that convert the power to the needed voltage levels for our components, the compressor, ionizer and the central control unit.

Additionally, the accessory battery supplies the functions needed for safety like wipers, lights and the horn.
