Flow cell vehicle reaches 350.000 km maintenance-free
Experimental car maker Nanoflowcell has announced that its prototype sports car Quantino 48V has covered 350.000 kilometres with practically no maintenance. And the vehicles’ somewhat mysterious power conversion unit could be mass-produced at a surprisingly low price.

The Quantino48V has been undergoing real-life endurance testing ever since it was homologated for road use in 2016, covering more than 200,000 kilometres on the road and 150,000 kilometres on a test bed. The total mileage required the regular replacement of consumable parts such as brakes and tires, as well as a wide assortment of minor repairs. However, despite its status as a prototype vehicle, the Quantino 48V’s powertrain ran with no problems throughout the duration of the test, the company writes in a blog.

Also the Nanoflowcell – as the company has baptized the unit that converts chemical into electrical energy in the vehicle – ran reliably throughout the entire test distance without any error alert and “virtually maintenance free”. The control software for the energy management system has been updated several times to improve system efficiency. As a result of these efficiency-driven updates, the vehicle reached an average consumption of just 8 to 10 kWh per 100 km.

In the same blog post, the company for the first time provided figures as to the price and value not of the entire car, but at least of the nanoflowcell energy conversion unit as certainly a rather crucial component: The unit could be mass-produced at a price around 600 euros, the company said. Since this component largely requires no maintenance, a vehicle built on this basis could be operated at rather low maintenance costs. The company even goes so far as to guarantee a service life of 50,000 operating hours. In the case at hand, this would correspond to a driving distance of 1.25 million kilometres, far more than the service life of today's vehicles.
