Hyundai Motor marks 20 years of Fuel Cell Electric Vehicle technology


The Hyundai Fuel Cell Truck launched last year is the culmination of two decades of research and development by the  Hyundai Motor in Fuel Cell Electric Vehicle (FCEV) technology.

Last September, Hyundai Hydrogen Mobility was formed – a joint venture between Hyundai Motor Company and H2 Energy. In turn, an additional partnership was forged with Hydrospider –  a joint venture of H2Energy, Alpiq and Linde to promote green hydrogen ecosystem in Switzerland and other European countries. As part of this partnership, Hyundai Hydrogen Mobility plans to bring 1,600 Hyundai H2 Xcient Fuel Cell Electric Trucks, marking the entry of the automaker into Europe’s clean mobility commercial vehicle sector.

The Hyundai H2 XCIENT Fuel Cell truck features a new 190 kW hydrogen fuel cell system with two 95 kW fuel cell stacks connected in parallel. It delivers a single-fuelling travel range of more than 400 km, with a fuel storage capacity of almost 35kg of hydrogen.

The first steps on this road to zero-emission, zero carbon road objective began with the establishment of a dedicated research team in 1998 and the creation of the Project Mercury collaboration between Hyundai and United Technologies Corporation (UTC). A number of vehicles were developed during the initial process, with system improvements in powertrain performance and increasing range capabilities culminating in the final vehicle, MercuryⅡ.  This  was based on the JM Tucson platform with an 80kW fuel cell system, 337km range and the ability to start from temperatures as low as -20oC.

In 2000, Hyundai also launched the Polaris project in conjunction with the Korean Government’s G7 Project. The G7 Project was an initiative to help close the technological gap that existed between Korea and other advanced countries, specifically in the field of eco-innovation. The Polaris project saw Hyundai independently develop complete fuel cell vehicle systems, which lead to several project vehicles such as Polaris Ⅱ which showcased a Hyundai fuel cell system with an output of 80kW and a range of 370km.

At the same time as the PolarisⅡ was in development, Hyundai produced its first fuel cell bus in 2005, with a 160kW fuel cell system and an operating range of 380km. As the sole automotive sponsor of the 2006 FIFA World Cup, as well as a fleet of conventionally fuelled vehicles, the company also provided a fuel cell bus as official transport for the duration of the tournament. This was the first time a Hyundai bus was certified for use on European roads, with the process taking only four months from offering the vehicle to its arrival in Germany.

As well as fuel cell systems, Hyundai also began in-house electric vehicle research in the early 1990’s. The two technologies became unified for the first time in the 2007 Tucson FCEV, which had a combined fuel cell and battery electric drivetrain output of 100kW and a range of 370km. Fuel cell bus development continued alongside passenger vehicles, with the 2009 2nd Generation Fuel Cell Bus offering a combined fuel cell system power of 200kW and an operating range of 380km.

2010 saw two milestones in the company’s fuel cell technology development: the accumulative distance covered by all Hyundai fuel cell vehicles reached the two million km mark and the new ix35 FCEV prototype was launched. This fuel cell vehicle was the first Hyundai to use high pressure 700bar fuel storage, boosting range to 635km from the 100kW fuel cell drivetrain.

Significantly in 2013, Hyundai became the first manufacturer to series produce the ix35 Fuel Cell electric vehicle. The 100kW fuel cell system and 700bar storage produced an NEDC certified 594km range.

In 2014, Hyundai unveiled the Intrado concept at the Geneva Motor Show. This concept showcased a focus on usability and adaptability, using advanced materials such as high strength steel and carbon fibre and new manufacturing and joining techniques that together have the potential to change the way cars are made. Intrado demonstrated a next-generation hydrogen fuel-cell powertrain with a hybrid Li-ion 36 kW battery, with a range of over 600 km.

By 2015, ix35 Fuel Cell sales were taking place across the world, including 13 countries in Europe, covering more than 1.2 million km’s.

Hyundai’s ongoing commitment to fuel cell development was shown in 2017, with the FE Fuel Cell concept that was shown at the Geneva Motor Show. Longer, lower and wider than the ix35 Fuel Cell, the FE (Future Eco) concept was shown as Hyundai’s Future Utility Vehicle (FUV) with a number of innovative vehicle technologies demonstrated alongside its powertrain.  These included integrated storage and charging space for an electric scooter which demonstrated how Hyundai Motor was starting to broaden the development of mobility solutions to match future lifestyles. The FE Fuel Cell concept featured new drivetrain technology including a fuel cell stack 20% lighter than that of the ix35 Fuel Cell, yet with an increased power density of 30% and a range of over 800km.

2018 was another landmark year for the company’s fuel cell story, with the launch of NEXO, the only fuel cell SUV in the world. The design for NEXO clearly followed on from the FE Fuel Cell concept, with many of the innovative technologies such as Lane Following Assist, Highway Driving Assist, Blind Spot View Monitor and Remote Smart Park Assist carried over from the concept to Hyundai’s 2nd commercially-available hydrogen fuel cell vehicle. In comparison to the ix35 Fuel Cell, NEXO offers a 25% faster acceleration rate, increased torque and 40% more range. Its 135kW powertrain and three reinforced carbon fibre/plastic fuel tanks allow NEXO to deliver a range of 665km.

Following on from the launch of NEXO, Hyundai Motor Group announced its long-term roadmap – ‘Fuel Cell Vision 2030’ – to reaffirm its commitment to accelerate the development of a hydrogen society by leveraging the group’s global leadership in fuel-cell technologies. Aligned with the roadmap, Hyundai Motor Group has pledged to drastically boost annual fuel-cell system production capacity to 700,000 units by 2030 and explore new business opportunities to supply fuel-cell systems to other transportation manufacturers of vehicles, drones, vessels, rolling stocks and forklifts. The demand for fuel-cell systems from sectors beyond transportation such as power generation and storage systems is also expected to emerge quickly.

In May 2019, the Hyundai Motor Group announced an investment of €80 million in Rimac and is also aiming to lead the high-performance electrified vehicle market. The companies have been working closely together to develop prototypes for both an electric version of Hyundai’s N sports car brand and a high-performance fuel cell electric vehicle with the intent to bring them to market.

Showcasing an alternative usage of our fuel cell stacks, Hyundai previewed the Hyundai Generator, a portable charging station for electric vehicles and the newest feature of emission free electric charging at the 2019 Frankfurt Motor Show. The Hyundai Generator consists of two fuel cell stacks and combined hydrogen storage, giving the ability to charge two EVs simultaneously at high speed. As comprehensive service provider of the new eTCR (Electric Touring Car Racing) championship, Hyundai will be providing the Hyundai Generator as a recharging system for all the cars to both showcase Hyundai’s technical leadership and accelerate the transition to clean e-technology.

As the Hyundai Motor Group positions itself as a global leader in clean vehicle technology, it also understands that there are considerable benefits in leveraging collective R&D capabilities across the industry. An example of this is the partnership between Hyundai Motor Group and Audi, which has seen both manufacturers share fuel cell technology developments to elevate their presence in the future fuel cell electric vehicle market.

Hyundai Motor Group also plans to strengthen its competitiveness in the fuel cell components industry, engaging in new business opportunities created by partnerships with other vehicle manufacturers. Hyundai Mobis, the leading FCEV components manufacturer of the Group, is continuously expanding its role in developing and supplying proprietary core components for Hyundai and other OEM’s fuel cell electric vehicles. Hyundai Mobis was the first company in the world to establish an integrated production system for core components of fuel cell electric vehicles and the company’s plant in Chungju, South Korea, already has the production capacity of 3,000 powertrain fuel cell complete (PFC) modules per year, and has capacity to produce tens of thousands of PFC modules down the road to meet forecast market demand. PFC modules are comprised of fuel stacks, drive motors, power electronic components and hydrogen fuel supply units. Jarlath Sweeney
