Fuel Cell /NiMH powered Race Car

1/10th 4WD model car powered by hybrid powertrain: Hydrogen Fuel Cell + NiMH battery.
Specific electronic board distributes the power demand between the battery and the fuel cell. The fuel cell is fed by two low-pressure H2 vessels (20 liters H2).
Full power/speed at 3:20 and 3:32.

this is a traxxas stampede vxl

You're right! well spotted. We use the Traxxas Stampede VXL as a base plateform. We adapt our fuel cell system on it. It works very well.

However, we are working on the Mark 2 of the Hytrax. It will probably be based on a 1/8th race track model to be more robust. It will also be lightest and has better performances. Mark 2 will be out for sale around mid 2013.

The traxxas brushed motors are not designed to be ran with more than a 3000-4000mah pack. Longer run times can result in motor damage. Heatsink and fan could be added for longer run times.

Hello,

Good comment: motor durability is often understated when increasing the runtime of a truck. We are using Velineon brushless motors from Traxxas. Compared to brushed motors, they can endure longer runs.

Merci!

De rien ! Si vous voulez plus d'info sur la voiture, n'hésitez pas à nous contacter via notre site web et adressez vous à Pierre - c'est moi -

Merci !

i want one.

So its just running directly off the 7cell nimh lol

How about 150-200 amps at 48 volts and capable of refilling from a 110vac, and/or 240vac out?

I have a car (real...like people get in it) that pulls about 120 amps continuous on the road, but it peaks around 200 amps up very steep hills, and can go up to 550 amps or so at full throttle from a stop. Capacitors would be used for acceleration...but what would a fuel cell+hydrogen tank+refill station thing cost that fits that?

The only thing that will need to be recharge is the Hydrogen tank, no more charging batteries, yes!

La batterie NiMH seule stocke 25Ah, ce qui donne entre 10 et 15 minutes d'autonomie en fonction de votre style de conduite. Les deux réservoirs contiennent 20 litres d'H2, soit 60Ah d'énergie chimique. La pile ayant un rendement d'environ 53%, et en tenant compte de la conso élec des accessoires, cela donne environ 30Ah pour la motorisation. Donc on double l'autonomie de la voiture avec l'emport de 20 litres d'H2.
