ASSEMBLY GUIDE

What you need:

Preparing a 10% ethanol solution:

Warning!
Do not allow pure ethanol to enter the fuel cell. The DEFC creates power using 5-15% alcohol only. A concentration higher than
15% could damage the fuel cell and cause it to stop working correctly. For best operation please use a mixture of 10% ethanol

and 90% Water. Keep ethanol away from the re or ame source while you are mixing the solution. Igniting the ethanol and the

ethanol solution is strongly forbidden.

Step 1: Fill the container with 6ml of pure ethanol (ll container to the 6ml level).
Step 2: Fill the remainder of the container with water to the 60ml level.
Step 3: Stir the liquid in the container thoroughly.

Kit Water Ethanol

Experiment 1: Create electricity from ethanol and water

STEP 1

STEP 2

Remove the fan blade from the box.
Push the blade onto the axis of the motor slowly and
carefully.

STEP 3

Pour the solution into the ethanol container.
Put the lid back to the container.

Note: When the solution starts dripping out of the tube,
close the purging valve by pushing the switch to the left
side. Then wait for 5 to 10 minutes before connecting the
wires.

Open the purging valve by pushing the switch to the
right side.

Make sure that the tubing connecting the container to the
fuel cell is securely attached.
Make sure the tubing connecting the tubing with purging
valve is securely connected to the fuel cell and the switch
on the purging valve is positioned at the right side close to
the solution tank.

STEP 4

Af ter waiting for 5-10 minutes, co nn ec t the two
crocodile clips that are attached to the motor to the two
terminal plates of the fuel cells current collector, which
are both located on the upper part of the fuel cell.

If you have waited for 5-10 minutes with the clips disconnected from the fuel cell, the fan should start rotating by itself once
connected. Make sure you repeat the waiting period of 5-10 minutes after each purging. Since the reaction is slow, the fan can
run for up to several hours without purging (see Experiment 3).
