The hydrogen fuel cell electric vehicle is, for Renault Group, an electric vehicle that combines a lithium-ion battery and a hydrogen fuel cell under one hood. By opting to use both technologies together, the brand combines the best of both worlds. Hence why, behind the iconic diamond logo on its electric utility vehicle Kangoo Z. Hydrogen , Renault has integrated a fuel cell. In this operational diagram of the Kangoo Z.
Hydrogen, the motor of the hydrogen-powered electric car is powered by its lithium-ion battery. As for the fuel cell, it provides an additional energy reserve that increases the range of the car providing more autonomy and shorter charging time. Hydrogen-powered vehicles provide the driver with the practical and financial advantages of electric power, plus the benefits offered by hydrogen in terms of flexibility and range.
Behind the wheel of a hydrogen-powered vehicle, the driver benefits above all from almost double the range. As part of the complementary relationship between the fuel cell and the lithium-ion battery, the electricity produced by the fuel cell using the stored hydrogen is added to the storage capacity of its main battery.
Hydrogen is equipped with a 30 kWh battery coupled with an onboard hydrogen storage capacity equivalent to The icing on the cake is the refueling speed. How exactly is a hydrogen fuel cell electric vehicle recharged? The answer differs between manufacturers. Firstly, recharging from a standard electric terminal to supply the lithium-ion battery an option facilitated by the number of accessible charging stations. Secondly, refueling at a hydrogen station to refill the gas tank takes just a few minutes — during the day, for example, when the driver needs to extend their trip.
Of course, hydrogen, highly-pressurized in its tank, is a volatile and flammable element. In case the fuel cell overheats or is removed, the hydrogen is dispersed and released in less than a minute. Before going into circulation, hydrogen cars must adhere to particularly strict European regulations. Kangoo Z. For over twenty years, technologies that use dihydrogen have been tested and approved on numerous occasions, often under extreme conditions space engineering, submarines, construction machinery.
Today, thanks to the experience accumulated from the pioneering Kangoo Z. Hydrogen since , Renault Group is going even further, announcing a partnership with the renowned world leader in fuel cells, Plug Power, who have rolled out over 40, fuel cell systems to date. The resulting Innovation Center will not only place its partners at the cutting edge of research and development, manufacturing, and the commercialization of hydrogen vehicles, but also at the forefront of related services charging infrastructures, hydrogen supply, etc.
While these two technologies give the impression of being diametrically opposed, they are actually complementary mobility modes. What is energy? Units and calculators. Use of energy. Energy and the environment. Also in What is energy? Forms of energy Sources of energy Laws of energy.

Although automakers could design an FCEV with plug-in capabilities to charge the battery, most FCEVs today use the battery for recapturing braking energy, providing extra power during short acceleration events, and to smooth out the power delivered from the fuel cell with the option to idle or turn off the fuel cell during low power needs.
The amount of energy stored onboard is determined by the size of the hydrogen fuel tank. This is different from an all-electric vehicle, where the amount of power and energy available are both closely related to the battery's size.
