As countries around the world are making efforts
towards decarbonization, Hyundai Motor Group
is also trying to change the energy paradigm for
carbon neutrality.
The Group has been preparing for an eco-friendly
era by starting the development of hydrogen fuel
cells in 1998, and recently announced
“Hydrogen Vision 2040,” which aims to popular-
ize hydrogen energy by 2040, at Hydrogen Wave.

The fuel cell system, the heart of hydrogen mobility, acts like the engine
of an internal combustion engine vehicle. Electric energy is generated through
a chemical reaction between hydrogen and oxygen, and this electric energy drives the motor.
The hydrogen fuel cell vehicle(FCEV) is attracting a lot of attention as an eco-friendly vehicle
with zero carbon emissions in the global market. Its biggest advantages are the
fast charging time of only 3 to 5 minutes, and the fact that it only discharges pure water.

Hyundai Motor Group has been working hard on de-
veloping technology using hydrogen energy since
1998. As a result, it succeeded in mass-producing hy-
drogen fuel cell vehicles for the first time in the world
in 2013.
In 2018, it launched the NEXO, a hydrogen fuel cell
vehicle based on the second-generation fuel cell sys-
tem. In 2020, it established a mass production sys-
tem for hydrogen fuel cell heavy-duty trucks for the
first time in the world.

the first internal combustion engine became a pop-

development of the next-generation fuel cell system
by Hyundai Motor Group is also focused on the popu-

In order to popularize hydrogen energy, it is essential to secure the price
competitiveness of the fuel cell system and durability that allows
long-term trouble-free driving.
As a result of continuous research, the Group has developed
a next-generation fuel cell system that overcomes existing limitations.

The core of a fuel cell system is a stack in which mul-
tiple cells are combined.
Thecellscreateapassageforsupplyinghydrogenand
oxygen, and consist of two metal bipolar plates that
support the stack structure, a gas diffusion layer(G-
DL), and a membrane electrode assembly(MEA) that
produces electricity by causing a chemical reaction
between hydrogen and oxygen.

Lowering the prices of these parts is of the utmost
importance.
Hyundai Motor Group secured price competitiveness
by replacing expensive titanium with a steel-based
material for the bipolar plate of the next-generation
fuelcellsystemandreducingtheamountofplatinum
used as a catalyst.

AsaresultofHyundaiMotorGroup’sresearchanddevelopment,the
price of fuel cell systems has decreased by about 98% compared to
20 years ago.

cell price decreased by 50%, and in 2013, the price of the first-gen-
eration fuel cell system installed in the Tucson ix hydrogen electric
vehicle decreased to 10%.

Fuel Cell System Price Trend The NEXO released in 2018 also achieved the current price through
this cost innovation process, and the price of the next-generation
fuel cell system is expected to remain at 2% of the initial prototype
level.
The plans to secure price competitiveness of hydrogen fuel cell
vehicles to the level of battery electric vehicles by 2030. In order
to achieve this, the company plans to develop parts that can be
mass-produced, apply them to fuel cells, and actively lower costs
by improving technologies such as valves and sensors.

Hyundai Motor Group’s fuel cell systems are also rap-
idly improving in terms of durability.
The very first fuel cell system was durable for 30,000
km(800hours), but the first-generation fuel cell sys-
tem secured the level of the internal combustion en-
gine with 100,000km(3,000hours) and 160,000km
(5,000hours) for the NEXO. Among the next-gener-
ation fuel cell systems, the high-endurance fuel cell
system for commercial vehicles aims to achieve a
driving range of about 500,000km.

The next-generation fuel cell system is divided into the
100kW class and the 200kW class based on output.
The volume of the 100kW class has been reduced to 70%
compared to the existing NEXO system. The 200kW class
has the same volume as the NEXO system but twice the
output.

Hyundai Motor Group’s next-generation fuel cell sys-
tem, which has reduced volume and price and in-
creased output and durability, continues to improve.
The next-generation fuel cell system can be used in
various fields other than hydrogen mobility.
Typical examples are the “power unit module” and
the “full flat system.”

The power unit module for MW-class large-capacity
power generation can build a 500kW to 1MW-class
large-capacity power generation system by expand-
ing the 100kW-class fuel cell system vertically and
horizontally according to the amount of power re-
quired.
In the future, it can be used for power plants that re-
quire a lot of electricity, auxiliary power for buildings
in remote areas where it is difficult to supply electric-
ity, and transportation such as large ships and trains.

The full-flat system is only about 25cm high, so it can
be widely used in various mobility applications such
as MPVs(Multi-Purpose Vehicles) and SUVs, as well as
PBVs(Purpose Built Vehicle), trams, buses and small
ships.

Hyundai Motor Group plans to expand the
application of fuel cell systems to UAMs, robots, aircraft
and large ships by 2040.
This is in order to realize a hydrogen society in which
hydrogen fuel cells are applied to all means of transportation,
and where hydrogen energy can be used easily
and conveniently for “Everyone, Everything, Everywhere.”
The next-generation fuel cell system will be the first step
in advancing such a hydrogen society.
