Only two prototypes of hydrogen-powered cars were presented at the latest engine macroferia, which was held at the end of 2017 in Frankfurt. Experts say that the technology based on the hydrogen battery has hardly evolved for 15 years, there is no infrastructure to refuel, the commercial offer is very scarce and economically it is an unfeasible fuel. However, the most optimistic still think that hydrogen has a future and a lot of development potential.
The cars propelled by hydrogen are electric traction cars in which the energy is obtained from the hydrogen stored in one or several tanks. The fuel of this type of vehicle is hydrogen, which provides the electrical energy that the engine needs for its operation thanks to a fuel cell system that converts hydrogen and air into electricity and water.
The most obvious advantage of this type of technology, apart from the absence of polluting emissions to the atmosphere, is the allowed autonomy (more than 600 km) and the fast recharge – unlike the ‘plug-in’ electric cars that need a time of recharge-, similar to a refill of gasoline or diesel.
