3. High pressure hydrogen
storage tanks
Compressed hydrogen tank system
is composed of three tanks which
are filled with hydrogen gas in a gas
station. Each tank is made of plastic
liner for blocking the hydrogen per-
meation and carbon fiber layer sus-
tain high pressures.
There are main parts to supply
hydrogen stably and to enable safety
such as magnetic valves, pressure
regulator, pressure sensors, pres-
sure relief valve, excess flow valve
and so on. The hydrogen in the tanks
comes into the pressure regulator
which has a pressure sensor.
4. Battery system
A 12 V battery integrated with the low
and high voltage batteries is installed
in the vehicle. The battery supplies
the electricity required for driving the
vehicle and stores the energy gener-
ated from the regenerative braking.
When the vehicle accelerates the
auxiliary power of the fuel cell sup-
plies the energy. The vehicle can
drive about 2 miles (3 km) in EV
mode until the high voltage battery is
discharged.
High voltage cables
The electric energy which is generat-
ed from fuel cell system or high volt-
age battery module is distributed to
the various components. Most of the
cables are located in the inside or bot-
tom of the components. These cables
use orange colored cover to distin-
guish from other lines. It is required to
handle the cables carefully with isola-
tion gloves.
