Fuel Cell Technology


 The all-new NEXO’s fuel cell system combines oxygen and hydrogen to create a flow of electrons that powers the electric drive motor and charges the 1.56kWh high voltage battery. It delivers best-in-class performance while producing no particulates or tailpipe emissions, other than purified air and droplets of clean water.

As you drive the NEXO, hydrogen travels from tanks to a fuel cell stack. Once in the fuel cell stack, hydrogen will go through an electrochemical reaction with the oxygen collected from the air intake. This reaction creates electricity, which then powers the vehicle's motor.


Hydrogen atoms enter the fuel cell at the anode where a chemical reaction strips them of their electrons. The hydrogen atoms are now "ionized," and carry a positive electrical charge which allows them to pass through the membrane. The negatively charged electrons provide the electrical current as they are forced to take the longer path.  


Hydrogen is as safe as gasoline, if not safer. NEXO's fuel is stored inside incredibly durable carbon fibre tanks, tested to withstand extreme heat and pressure. Since these tanks are highly pressurized and hydrogen is much lighter than air, the fuel would dissipate into the air if a tank was punctured. 


Since launching the world’s first mass-produced fuel cell in 2013, we've overhauled its constituent parts to make the system smaller, lighter and stronger. As a result, our second generation fuel cell has the world’s highest system efficiency, consuming as little as 1kg of hydrogen per 100km. Along with its five-minute fill-up time and impressive range of 666 km (WLTP), the all-new NEXO offers a viable alternative to the combustion engine for everyday commuting and long drives alike.

This is designed to provide figures closer to real-world driving behaviour. Figures shown are for comparability purposes; only compare fuel consumption, CO2 and electric range figures with other cars tested to the same technical procedures.

Refuelling the NEXO

The NEXO not only embodies Hyundai’s commitment to advanced eco-friendly vehicle development – but it also reinforces the company’s leadership in fuel cell electric vehicles (FCEV). Hyundai is a pioneer in fuel cell technology, beginning R&D for it in 1998. And in 2013, we pioneered the commercialisation of hydrogen fuel cell vehicles, bringing the ix35 Fuel Cell to market. Hyundai became the world's first carmaker with a mass production hydrogen fuel cell vehicle – an unprecedented endeavor in the automotive industry.

World's 1st mass production FCEV vehicle

In 2013, the ix35 Fuel Cell (also known as the Tucson Fuel Cell in some markets) became the first mass-produced hydrogen-electric car in the world.

Most fuel cell vehicles sold

By the end of 2017, 500 hydrogen-electric cars were registered from Hyundai in Europe. It's more than all the other brands combined. Hyundai sells them in 18 countries, of which 13 are in Europe.

Sustained Commitment to the environment

Hyundai Motor Company has been involved in the development of hydrogen-electric cars since 1998. The role of industry leader in environmentally friendly technology is something we take seriously.


Here at Hyundai we are committed to being the global brand leader in advanced technology and eco-friend vehicles.
