The fuel cell will compete with many
other types of energy conversion
devices.
oThe gas turbine in your city's power plant
o The gasoline engine in your caro The battery in your laptop.
What a FUEL CELL can do ?

COMBUSTION engines like the
turbine and the gasoline engine
burn fuels and use the pressure
created by the expansion of the
gases to do mechanical work.

BATTERIES converted chemical
energy back into electrical energywhen needed. Fuel cells should do
both tasks more efficiently.

A fuel cellprovides a DC(direct current) voltage that can
be used to power motors, lights
or any number of electrical
appliances.

A FUEL CELL WORKS
JUST LIKE A BATTERY.
IT DOES NOT START
IT SELVES. IT NEED
SOME STARTING
DEVICES.

FOR OUTDOOR USE AND
DAY-TIME SOLAR ENERGY
CAN BE USED AND FOR
INDOOR AND NIGHT TIME A
BATTERY CAN BE USED TO
START THE HYDROLYSISPROCESS.

Chemistry
of a Fuel CellAnode side:
2H2 => 4H+
+ 4e-
Cathode side:O2 + 4H
+ + 4e- => 2H2O
Net reaction:2H2 + O2 => 2H2O
