Fuel cell electric vehicles using hydrogen
and oxygen in the air under t
he action
of catalyst hitches in a fuel cell electrochemical
reaction to pr
oduce electricity, and as
the main source of power drive car.
Fuel cell electric vehicle is in
essence a kind of electric cars, in body,
p
ower transmission system, control
system, etc., the fuel cell electric
veh
icle and general electric car basic
same, the main difference is that the
principle of power battery is
different. Generally speaking, the fuel cell
i
s through electrochemical reactions
convert chemical energy into
electr
icity, electrochemical reaction
required reductant with hydrogen,
oxyge
n oxidant is used, so the earliest
development of fuel cell electric
vehicl
e is more directly using hydrogen
fuel, hydrogen storage can use
liquefi
ed hydrogen, compressed hydrogen
or metal hydride hydrogen storage
, etc.
Pure fuel cell car fuel cell is only a
source of power, the car all the echo
power of fuel cell. At present, a lot of fuel cell
vehicles driven by mixed
form, on the
basis of the fuel cell, increases a set of battery
or super ca
pacitor as another source of
power. The main structure: energy control
unit, air compressor, fuel cell stack,
high pressure hydrogen storage bo
ttle,
power battery and motor. High pressure hydrogen
storage bottle pr
ovided with fuel, and
outside of the power supply, power battery for car
acceleration, climbing and running at a
high speed. Slide on the vehicle
, the
energy control unit will drive motor into
generator, which will be pa
