Pour in the water and watch it separate into hydrogen and oxygen, forming a gas to power your vehicle across the floor. It uses a reversible PEM fuel cell that combines electrolysis and power conversion into one single device. The oxygen and hydrogen gases are formed in two transparent water containers. This car will steer independently once in operation. When the car hits a barrier, it will adjust its way by reversing away 90 degrees. The fuel cell car is safe and the fuel cell tanks do not hold enough gas to be dangerous.
