The Hydrogen Refueling Station supplies very small quantities of hydrogen fuel to the H-racer’s fuel tank. When producing fuel “on tap”, the refueling station is visually dynamic with flashing blue LEDs in the water tank and bubbles rising through the pure water. The fuel is produced from water using energy from the sun (solar panel included).

If the sunlight is not available there is an optional battery pack to insert 2 "AA" batteries to substitute for the lack of sunlight.

The volume of Hydrogen stored in the H-racer is very small and safe that adds to the concept of just how efficient this cutting-edge technology is. The H-racer is the working miniature version of what is being developed in real-size cars of the future. This palm-size fuel cell car contains an onboard hydrogen storage tank, a fuel cell system connected to the car’s electric motor, and a hydrogen refueling system linking the car’s storage tank to an external hydrogen refueling station.Given its small size, the H-racer is also very safe as only tiny quantities of hydrogen are needed to power the car.
