OBJECT
TO MAKE HYDROGEN FUEL CELL CAR.
HYDROGEN FUEL CELL
ITS CONSTRUCTION AND
WORKING
APPARATUS
To make the fuel cell, we need the following:
• One foot of platinum coated nickel wire, or pure
platinum wire. Since this is not a common household
item, we carry platinum coated nickel wire.
• A popsicle stick or similar small piece of wood or plastic.
• A 9 volt battery clip.
• A 9 volt battery.
• Some transparent sticky tape.
• A glass of water.
• A volt meter.
HYDROGEN FUEL CELL
STEPS FOR MAKNIG HYDROGEN FUEL CELL
STEP 1
The first step is to cut the
platinum coated wire into two six
inch long pieces, and wind each
piece into a little coiled spring that
will be the electrodes in our fuel
cell. Next, we cut the leads of the
battery clip in half and strip the
insulation off of the cut ends. Then
we twist the bare battery lead wires
onto the ends of the platinum
coated electrodes, as shown in the
photo. The battery clip will be
attached to the electrodes, and two
wires will also be attached to the
electrodes, and will later be used to
connect to the volt meter.
• STEP 2
The electrodes are then
taped securely to the
popsicle stick. Last, the
popsicle stick is taped
securely to the glass of
water, so that the
electrodes dangle in the
water for nearly their entire
length. The twisted wire
connections must stay out
of the water, so only the
platinum coated electrodes
are in the water.
STEP 3
Now connect the red wire to the positive terminal of
the volt meter, and the black wire to the negative (or
"common") terminal of the volt meter. The volt meter
should read 0 volts at this point, although a tiny
amount of voltage may show up, such as 0.01 volts.
fuel cell is now complete.
• To operate the fuel cell, we need
to cause bubbles of hydrogen to
cling to one electrode, and
bubbles of oxygen to cling to the
other. There is a very simple way
to do this.
• We touch the 9 volt battery to
the battery clip (we don't need to
actually clip it on, since it will
only be needed for a second or
two).
• Touching the battery to the clip
causes the water at the
electrodes to split into hydrogen
and oxygen, a process
called electrolysis. You can see
the bubbles form at the
electrodes while the battery is
attached.
WORKING OF HYDROGEN FUEL CELL
FUEL CELLS & REDOX REACTION
OXIDATION:
 Anode (negative electrode): e- leave the cell
 H2  2H+
+ 2e-
REDUCTION:
 Cathode (positive electrode): e- enter the cell
 4H+
+ 4e-
+ O2  2H2O
FUEL CELLS & CATALYSTS (rate of reaction):
The splitting of H2 into p+ and e- at the anode is
typically speeded up by the presence of a catalyst
(typically metal placed on the anode, or the
electrode itself)
Electrolyte – permit only appropriate ions to pass
between anode and cathode; otherwise the
chemical reaction may be disrupted
