37. Is it possible that water, oil, etc. may be
introduced to the hydrogen gas tank via
the fuel filler? If yes, what do I need to
do to prevent this?
Normally, water and oil cannot flow into the hydrogen tank via the
fuel filler, but it can flow in while refueling. Be careful not to intro-
duce any contaminants via the fuel filler.
38. While refueling the hydrogen, I hear
irregular abnormal noises. Is this noise
cause for concern?
The hydrogen gas is in high pressure (70 MPa) condition when refu-
eled to the vehicle's storage tank. Therefore, you will hear the sound
of the gas flowing in the beginning. Abnormal noise is occurred due
to the gas flow because of the difference in refueling pressure, etc.
depending on the gas pressure condition at the refueling station and
this is very normal.
