Energy
Hydrogen Fuel Cell
SE-8573
A hydrogen fuel cell is a clean and efficient
way of storing energy and generating
electricity. With this Hydrogen Fuel Cell,
students see a real-world example of
cutting-edge energy technology.
Electricity from the solar panel is used in
the process of electrolysis to split water
into oxygen and hydrogen.
The hydrogen is used as fuel in the fuel cell.
The process that takes place in the fuel cell
is the opposite of electrolysis: the hydrogen
is combined with oxygen to make water
and produce electricity.
In this demonstration, the electricity
produced by the fuel cell is used to operate
a fan. The fuel cell has an efficiency of
about 50%.
This apparatus uses Proton Exchange
Membrane (PEM) technology. A PEM is a
proton-conducting polymer membrane that
is covered with a layer of catalyst material
on both sides. These two layers form the
cell’s cathode and anode. One PEM is used
to separate the hydrogen from the water,
and a second PEM is used to re-combine
the hydrogen with oxygen to make water.

in minutes
The hydrogen and oxygen accumulate
in their respective tanks. Since there are
two hydrogen atoms for each oxygen atom
in a water molecule, twice as much hydrogen
gas is collected. The hydrogen gas
collection tank will fill completely in about
two minutes.
Disconnect the power supply and the
Hyrunner is ready to hit the road!
PASCO’s Hyrunner Hydrogen Car is an
outstanding example of a promising energy
source for the future. The hydrogen fuel cell
is an amazing device that combines hydrogen
with oxygen to produce water and energy.
Hydrogen fuel cells boast an efficiency that
is roughly twice that of internal combustion
engines.
The energy from a fuel cell can be used to
do work on any system. In the case of the
Hyrunner, the energy is used to move the
car across the floor at a maximum speed of
20 cm/s. The Hyrunner is well-constructed,
with all components visible for student
inspection and a more thorough
understanding of its workings.
How it Works
Place distilled water into the two storage
tanks to force any air out of the gas collection
chambers.
Next, plug the included power supply into
the hydrogen fuel cell. Using the energy
from the power supply, the water in the
storage tanks is electrolyzed, creating both
hydrogen and oxygen gas.
